Question

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)?

Enter your answer, as a decimal, in the box.
P(X=0)


how can i solve this ?

Answer 1

Assuming P(X=0) means neither ordered coffee = (1-.8)(1-.8) = ?

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
