Answer:112
Step-by-step explanation:
I did it and we doing the same test rn haha. What did you get for the grant one?
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
It’s B hopefully this helps you!!.:;)))))
