Question

find the mean of 1st 5 odd prime numbers

Answer 1

SOLUTION :

Prime Numbers : Numbers which have two factors, 1 and the number itself

Example : 5 , 11 , 7 etc

Now,

First Prime odd number are

2, 3, 5, 7, 11

We know that,

$\bf{Mean} = \frac{ \bf{Sum \:of \: all \: obsevations} }{Number \: of \: observations}$

$\bf{Mean} = \frac{ \bf{2 + 3 + 5 + 7 + 11} }{ \bf{5} }$

$\bf{Mean} = \frac{ \bf{28} }{ \bf{5} } }$

$\bf{Mean}$ = 5.6

Hence

The mean of first 5 odd prime numbers is 5.6
