Answer 2

To find : mean of the first five prime numbers.​

Solution :  

• According to question we have to find mean of first five prime numbers.​  
• prime numbers are the numbers having only two factors that is $1$ and the number itself .
• Therefore , first five prime numbers are : $2 , 3 ,5,7,11$ .

• Now we find mean of  $2 , 3 ,5,7,11$ using following formula :
• $Mean \ or \ average =\frac{sum \ o f\ observations}{number \ of \ observations}$

                                     $= \frac{2+3+5+7+11}{5} \\= \frac{28}{5} \\= 5.6$

Hence , mean of the first five prime numbers  is $5.6$ .
