Answer 2

Answer:

$\frac{20}{35}=\frac{4}{7}$

Step-by-step explanation:

If the instructor chooses a person to be in charge of a project, he has 20 + 15 = 35 people to choose from. The probability that the person will be a man, therefore, is 20 out of 35. As a simplified fraction:

$\frac{20}{35}\div\frac{5}{5}=\frac{4}{7}$

In other words, the simple probability that the person will be a man is 4 out of 7.
