Question

In math class of seven woman and nine men, if one person is selected at random to come the board to show the solution to a problem, what is the probability that the student is a man?

Answer 1

3/5

Explanation:

Given

Number of women in the math class = 7

Number of men = 9

Total = 9 + 7 = 15

Probability of selecting a man at random to come to the board and show solution to a math problem

= number of men/total number of persons in the class

That’s

9/15

Divide both the numerator and denominator by 3

3/5

The probability of picking a man student is 3/5
