Answer 1

The answer is 100/9 or 11(1/9)

Sum of first 9 prime numbers:
2+3+5+7+11+13+17+19+23= 100

Average = 100/9

Answer 2

first nine prime numbers : 2 , 3 , 5 , 7 , 11 , 13 , 17, 19 , 23
              we know,
average = sum of numbers/total numbers 
              =(2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 )/9
              = 100/9
              = 11.111
