Question:

Approximately 30% of the calls to an airline reservation phone line result in a reservation being made.  Suppose that an operator handles 10 calls. What is the probability that none of the 10 calls result in a reservation?

Step-by-step explanation:

Given

Represent probability of reservation with p and Number of calls  with n

First, we need to convert p to decimal

In probability; opposite probability add up to 1;

In other words,

Where q represents probability of no reservation

Substitute 0.30 for p

The probability that out of the 10 calls, no reservation is made is calculated as;
