People with type O-negative blood are universal donors whose blood can be safely given to anyone. Only 8% of the population have O-negative blood. A blood center is visited by 5 donors in an afternoon. What is the probability that there are no universal donors among them? Round your answer to four decimal places.

Step-by-step explanation:

Given

Represent P(O-Negative) with p

So:

Convert to decimal

Required

Determine the probability that none out of 5 is O-Negative

First, we need to determine the probability that one person is not O-Negative

Represent this with q

To determine the probability that none out of five, we have:

Where

So, we have:

--- Approximated
