Question

In Gainesville, one in four people have blonde hair.

What is the chance that if four people are chosen at random from Gainesville, at least one person has blonde hair?

Answer 1

25% or 1:4

Explanation:

When it says 1 in 4, that can be expressed as a 25% chance or as a ratio of 1:4. Since you are taking 4 people at random, and the chance is one in four, you have a 1/4th chance, therefore a 25% chance or a 1:4.
