Question 1062260
the prime numbers on the die are
:
2, 3, 5 , 7 , 11
:
the probability(Pr) of rolling a prime number on 1 roll is 5/12
:
we use the binomial probability distribution
:
Pr ( 70 = < X < = 90 ) = Pr ( X < = 90 ) - Pr ( X < 70 ) 
:
use binomial probability distribution with n=200, r=70 or 90, p = 5/12, q = 7/12
:
Pr ( 70 = < X < = 90 ) = 0.82 - 0.02 = 0.80
