Answer 2

Hey there !!

Mean :- the average of a series .

Here from 1 to 10 , there are 2,3,5,7, total 4 prime numbers .

so ,

mean of all prime numbers less than 10 = sum of all prime no. less than 10/ sum of no. of prime no.

mean = 2+3+5+7/4 => 17/4

mean => 4.25

hence the mean of all prime no. less than 10 is 4.25 .
