Question

What percent is the probability that a female patient will have type O blood? Round your answer to the nearest tenth of a percent

Answer 1

41.8%

Explanation:

To find the probability for a female patient to have O blood, find the number of female patients who do have O blood and divide it by the the number of female patients.

The number of female and O blood is 140.

The number of female patients is 335.

The probability is 140/335 = 0.4179.

The percent is found by multiplying by 100.

0.4179*100 = 41.79% rounds as 41.8%
