Answer:
41.8%
Step-by-step 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%
