Answer:
P(N = n) =
Step-by-step explanation:
to find out
Find the PMF PN (n)
solution
PN (n)
here N is random variable
and n is the number of times
so here N random variable is denote by the same package that is N (P)
so here
probability of N is
P(N ) = Ф ( N = n) .................. 1
here n is = 1, 2,3, 4,...................... and so on
so that here P(N = n) will be
P(N = n) =
Answer:
yea
Step-by-step explanation:
You can see that the price of the first pack is less than twice the price of the second whereas you get lot more than twice much more pencils for it (30>24) so the first deal is clearly way better.
