Question

Find the mean of first 5 Prime numbers

Answer 1

first five prime numbers are 2,3,5,7,11
sum of the first five prime nos. = 2+3+5+7+11 = 28
total no of observations = 5
therefore, mean = sum of observations / total no of observations 
i.e. 28/5 = 5.6
i.e. mean of first five prime nos is 5.6......

hope this helps !☺

Answer 2

First five prime numbers = 2,3,5,7,11

Mean = (2+3+5+7+11)/5

= 28/5
= 5.6
