What is the mean of prime numbers between 1 to 20?

                                                       

║⊕ANSWER⊕║

Prime numbers from 1 to 20 = {2, 3 ,5 ,7 ,11 ,13 ,17 , 19}

                                                  = 8

Mean = Total no: of outcomes / No: of observations

Average of prime numbers = 2 + 3 + 5 + 7 + 11 + 13 + 17 + 19/ 8

                                               = 77 / 8

                                                = 9.625

∴ Option a) is your answer.
