Answer 2

The probability that the person is a male is 0.67.

The probability that the person is a male is 0.67.Given:

The percentage of women smokers= 20%

The percentage of men smokers= 40%

To find:

The probability that the person is a male.

Solution:

Probability is the measure that how likely an event can occur.

Probability is always less than or equal to 1.

The formula for probability is=

$\frac{sum \: of \: all \: observations}{total \: number \: of \: observations}$

The probability of women smokers= $\frac{20}{100} = 0.02$

The probability of women smokers= $\frac{20}{100} = 0.02$The probability of men smokers= $\frac{40}{100} = 0.04$

The probability of women smokers= $\frac{20}{100} = 0.02$The probability of men smokers= $\frac{40}{100} = 0.04$The probability of the total number of smokers= 0.02+0.04= 0.06

number of smokers= 0.02+0.04= 0.06The probability that the person is a male= $\frac{0.02}{0.06} = 0.67$

number of smokers= 0.02+0.04= 0.06The probability that the person is a male= $\frac{0.02}{0.06} = 0.67$Therefore, the probability that the person is a male is 0.67.
