Answer 2

Answer:

$\huge\bold\red{\frac{75}{7}}$

Step-by-step explanation:

Mean - It is the sum of total numbers divded by total number of digits.

Or, we can say

$Mean=\frac{Sum\:of\:\:total\:numbers}{Total\:number\:of\:digits}$

Prime Numbers - Those numbers which have factors equal to 1 and the number itself. For example, 5, 7 .

Now, Prime numbers between 1 and 20 are 3, 5, 7, 11, 13, 17 and 19.

Total number of prime numbers = 7

Therefore,

$Mean=\frac{3+5+7+11+13+17+19}{7}\\=> Mean = \frac{75}{7}$
