Question

if a person is randomly selected, find the probability that his or her birthday is not in may. ignore leap years.
d. $\frac{11}{12}$
c. $\frac{31}{365}$
b. $\frac{31}{334}$
a. $\frac{334}{365}$

Explanation:

Step1: Determine total days in a non - leap year

There are 365 days in a non - leap year.

Step2: Determine days in May

May has 31 days.

Step3: Calculate days not in May

The number of days not in May is $365 - 31=334$ days.

Step4: Calculate probability

The probability $P$ that a randomly selected person's birthday is not in May is the number of days not in May divided by the total number of days in a year. So $P=\frac{334}{365}$.

Answer:

a. $\frac{334}{365}$
