Answer 1

$\huge\mathbb\blue{AnSweR}$

_______________________

→ Prime numbers between 10 to 20 are :-

11 , 13 , 17 and 19

→ Formula of mean .

As we have an individual series ( because there is no frequency) so we will use the formula i.e

$\mathcal \pink{ \frac{sum \: of \: all \: numbers}{number \: of \: data \: given \: } }$

→ Sum of all numbers = 11 + 13 + 17 + 19

→ 60

→ Number of data = 4

Now applying formula

$> \frac{60}{4}$

→ 15

So , the mean of the prime numbers between 10 - 20 is 15 .
