What is the Probability of a Randomly Selected Person Having a Birthday in June?

In this article, we will explore the probability of a randomly selected person having a birthday in June. To calculate this probability, we need to consider the total number of days in a year and the number of days in June. We will also assume that the person was not born in a leap year, which means that the year has 365 days.

To calculate the probability of a randomly selected person having a birthday in June, we need to understand the concept of probability. Probability is a measure of the likelihood of an event occurring. In this case, the event is having a birthday in June.

To calculate the probability of a randomly selected person having a birthday in June, we need to divide the number of days in June by the total number of days in a year.

Number of Days in June

June has 30 days.

Total Number of Days in a Year

A year has 365 days.

Calculating the Probability

Now, we can calculate the probability of a randomly selected person having a birthday in June.

Probability = (Number of days in June) / (Total number of days in a year) = 30 / 365 = 0.0821917808219178

Simplifying the Fraction

We can simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5.

Probability = (30 ÷ 5) / (365 ÷ 5) = 6 / 73 = 0.0821917808219178

In conclusion, the probability of a randomly selected person having a birthday in June is approximately 0.0822 or 6/73.

Why is this Probability Important?

This probability is important because it gives us an idea of the likelihood of a person having a birthday in June. This can be useful in various fields such as statistics, probability, and data analysis.
