Example 3

What is the probability of choosing a month that starts with the letter J?

Solution

There are exactly three months that start with the letter J, namely, January, June, and July. This means that

n = 3.

Since there are 12 months in a year, the probability of choosing a month that starts with the letter J is

P (A) = \frac{n}{N} = \frac{3}{12} = \frac{1}{4} .
