Question

the probability that a boy will get scholarship is 0.75 and that a girl will get is 0.72 what is the probability that al least one of them will get scholarship is ?

Answer 1

The probability that at least one of them will get scholarship is 0.93

How to determine the probability

The given parameters are:

P(Boy) = 0.75

P(Girl) = 0.72

The probability that at least one of them will get scholarship is calculated using

P = P(Boy only) or P(Girl only) or P(Both)

This is then calculated as:

P = 0.75 * (1 - 0.72) + 0.72 * (1 - 0.75) + 0.72 * 0.75

Evaluate the products

P = 0.21 + 0.18 + 0.54

Evaluate the sum

P = 0.93

Hence, the probability that at least one of them will get scholarship is 0.93
