Question 985444: At a certain breakfast restaurant, the probability of a customer ordering coffee is 0.8. When the restaurant seats two new customers, X is the number of customers ordering coffee. What is P(X=0)? Express answer as a decimal.
P(X=0)=[1] Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! P(X=0)=(1-p)^2, where p is the probability of a customer's ordering coffee.
=0.2^2=0.04, assuming independence.
