-What is the probability that at least 5 of the men will say no?

Answer 1

25%

Explanation:

There is 20 men total, at least 5 will say no .

So you get a fraction : 5/20.

You divide both the nominator and denominator by 5 (bc 5 goes into 20).

So you end up with 1/4.

Convert 1/4 to a percent and you get .25 or 25%.
