If you are an eCommerce, there will be fewer people who visited the “Check Out” page than the “Shopping Cart”. If you built an audience with your Facebook pixel, you audience size should be different.
this is basically the point
--> the people who are checking out are the people you want to target, so that subset is smaller than say all the people mildly interested

r of success
x is successes in hypergeometric
There is only the one arrangement withxfailures followed by1success. Thisarrangement has probability
so just x failures followed by 1 success
same as negative binomial but k = 1 so x+1-1 = x of course where x is the number of failures
different arrangements ofx S’s and(nx)F’sover thentrials.
how many ways can we order successes over n trials
x+k1x
how many ways can we order the fucking failures given x+k-1 trials
k1)successes, in any order
last success is fixed
Xbe the number of failures obtained before thek’th success.
follows NB if you have S/F with independent trials, with replacement

reqt of all probability functions
function(f(x)orX(a)) and thevalue of a function( for examplef(2)orX(a) = 2)
for a = THH
Proof of (a)
so our sample space has8!5!3!= 56equally possible outcome
= (8C5)(3C3) = 561 which is also valid
herefore by themultiplication rule there are36(3)56(3)ways to get a number which is even and>3000
flaw: you cannot make one 4 digit number in p ways and then turn around and make another 4 digit number in q ways and then claim that the there pxq ways to make a single 4 digit number. it doesnt make sense
(4;4)
only that particular even number is not available, so:
[3,7] and even is only 4 and 6--> subtract 2
o the probability it is even is theprobability it is either2;4;or6or37
there are multiple ways to do it and some are simpler than others
if you have einstellung with one, skip it and move on and you may find a simpler solution
--> same deal in (b)
Since each of1;2;:::;7isequally likely to be the first digit, we get the probability the number is greater than3000is57
same deal as in (a)
Case 1:all three letters are the same.
split into cases when desired/required
Now we can use the same technique to arrange the remaining eight letters. Having placed two of theS’s, there remain eight free boxes, in which we are to place three T’s in83ways, two I’s in52ways,one C in31ways, one A in21ways and finally the remaining S in the last empty box in11way.There are
Position is unique, not the letters. The letters are indistinguishable.
i.e: S1=S2=S3 but position 1 != pos2!=pos3
There are9(4)pin numbers that do not contain 1 and so there are10(4)9(4)that do contain a1. Therefor
the complement of all pins without 1s
so all pins with 1s which is the same as (9^(3)*2)/(10^(4)) since there are two (2) places for the 1 to go
Since we have a uniform probability model
every simple event is equally likely
We avoid this complication by starting with the second box
.
two or more transition leaving the same state can have the same label yet lead to different states
must also consider/connais that all DFAs are NFAs
e-NFA
basically your start pos is multiple start pos's

solns?
(q0,1) U T(q1,1) U T(q2
yourew moving from any number of these states so of course the final state set is going to be the result of a union
A =
accepting state
{q2
intrsxn w accepting states, right?
all the possible subsets of Q
so here a subset is basically just concatenating instead of putting into a set

this is a simplistic diagram
you could have 1 taking you back to q0 from q1 and q2 since you want 2 0s at the end

i dont really understand this proof

so basically its already known that Span B is a subset of S, basically by definition:
We already know that all the vectors in B are in S and since S is closed under linear combinations, Span B is a subset of S (i.e: can be written as an LC of the vectors in S). (you cannot go beyond)
the best you can do with n-1 vectors (even if you are touching all 4 dimensions) is to create a hyperplane assuming linear independence
page 31
thm 5 explanation:
so we find that ci=di for every vector 1<=i<=k in S
the proof makes sense in example 14 since we show that
page 16
example 17 makes sense since you show that

bindings
essentially giving out all the bindings
P(BjA)P(A) +P(BjA)P(A)
prob that b occurs given a + prob that b occurs given a complement
this just reduces into p(b)
P(A)P(BjA
P(A)P(B|A) = P(A)P(AnB)/P(A) = P(A)
(AiAjAkAl) +
notice it keeps going so you would then add back in P(AiAjAkAlAm)
(where the subscripts are all distinct, for examplei < j < k < l).
clever way to ensure distinctiveness
P(D) = 1PD= 19(4)10(4)
yes my method works (of choosing one of the four locations) so:
P(D)=4*9^(4)/10^(4) is right also
since we can only have one 1, otherwise you would need to use their method of finding the complement
(23) + (32) = 12ways
makes sense
We need to have more efficient ways of determining the number of outcomes inSor in a compoundevent without having to list them all. Chapter 3 considers ways to do this, and then Chapter 4 developsother ways to manipulate and calculate probabilities
happens later, chapter 2 is genuinely soft
Solution 1:
In this solution we simply flesh out the sample space and assign a prob'y dist'n to the events.
Then we simply count up the number of events which fulfill our criteria and produce the probability.
f2,3,4;:::;A;2~;:::;A|g
here, the same event is a compound event.
note that only one of these events will occur in a single trial in both cases, but there are multiple ways in which the event can occur (club)
={spade, heart, diamond, club}.
as you can see with this example and the next,: the sample spaces need not be unique in order to produce the same result.
598
you do indeed have 5 options for the even digit, and then 9,8,7 for the rest of the digits
Structural recursion
structural recursion with an accumulator is called accumulative recursion, stores subproblems
Tokens
LIST OF TOKEN TYPES
break up an assembly language instruction into components and classifying these components.
so that: you can ID errors you can output the appropriate output when desired
lexeme
basically a fancy way of saying "word"
MSB
MSB is a 1 so you dupe that and you will get a 2s comp (i.e: signed) -1, i.e.: 0xf
0x87654321
0x87654321 has the MSB as 1 which will trigger the different behaviours
recall that 8= 2^3 and is uniquely represented as the nibble 1000
char(instr>> 24) << char(instr>> 16) << char(instr>> 8) << char(instr);
printing from MSB to LSB (>>24 comes first!)

it is saying that these are ALL EQUAL

THE FINALE!
s is 2 = 000102shifted 21 bits left
consider that a 0 bit shift left would not add any additional 0s to the right.
1 bit shift left would put 11 zero there.
26? 26 zeroes
(0x0F)
number is 15, so we're just going to keep the right nibble on
3124beyond
why is beyond on 24 when its just a label??
ANSWER: You don't want to be going back up to 20 and rerunning it every time. That would be wrong
// y gets 0, and (bar, 0)// gets added to st.
builtin mechanism where if its not there it will get added
each instruction is exactly 4 bytes long
aka 32 bits
