Answer 1

Complete step-by-step answer:

We have to find the mean of the first five prime numbers.

Prime numbers are the numbers that have only two factors, the number 1 and the number itself.

The first five prime numbers are 2, 3, 5, 7 and 11.

Mean is calculated by adding all the observations by the total number of observations.

The formula of mean is Sum of observationsNumber of observations

Therefore, we will calculate the sum of the first five prime numbers.

⇒2+3+5+7+11⇒28

Now, we will divide this by 5 as there are a total 5 numbers.

285=5.6

Hence, the mean of first five prime numbers is 5.6
