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

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
