Answer: the maximum number of guests that he can invite would be 9
Step-by-step explanation:
Darnel's retirement party cost $33, plus an additional $1 for each guest he invites. Assuming Darnel wants to invite x guests to his retirement party, the total amount of money that Darnel would spend is
33 + x
if darnel can afford to spend a total of $42 on his retirement party, then
42 = 33 + x
x = 42 - 33 = 9
Solution :
Given :
P (never married) = P = 0.44
Sample size, n = 15
Let (n = 15, P = 0.44)
P(X = x) =
a). The probability that exactly two of them have been married is
P(X=2) =
= 0.0108
b). That at most two of them have never been married.
= 0.000167+0.001969+0.010828
= 0.012964
= 0.0130
c). That at least 13 of them have been married.
P(married) = 1 - P(never married)
= 1 - 0.44
= 0.56
= 0.012964
=0.0130
