For a group of 100 randomly chosen people, compute: (a) the expected number of days of the year which are birthdays of exactly two people.(b) the expected number of days in the year which arenotbirthdays of anyone.(c) the expected number of days in the year which are birthdays of someone in the group.(d) let x be a geometric random variable with pdf: p(x=k) = qk−1p, k= 1,2,3, . ..prove that the moment-generating function of x is m(t) = pet / (1−qet), t < −logq. can you explain why m(t) does not exist if t≥ −logq?

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
