Question

If one of the 1008 subjects is randomly selected, find the probability that the person chosen is a woman given that the person is a light smoker. Round to the nearest thousandth.

Answer 1

The probability is 0.4841.

Explanation:

The provided table is:

From above table, it is known that

Number of subjects are 1008.

The probability that the person chosen is a woman given that the person is a light smoker can be calculated as:

`P(Woman| Light smoker)=(P(Woman and light smoker))/(P(Light smoker)) \\P(Woman| Light smoker)= ((76)/(1008) )/((157)/(1008) ) = 0.4841`

Thus, required probability is 0.4841.
