Explanation / Answer

p ( not red snapper) = .68

a. They served red snapper next time is 1-P( not red snapper) = 1-.68 = 0.32

b. P(X>=1) = ? X is R.V for no. of customers served actual snapper

We will use binomial dist pdf func.

So, P(X>=1) = 1-P(X<1) = 1- P(X=0) = 1- ( 7C0*.32^0 *.68^7) = 1- ( 1*1*.067) = 0.9330
