Question

ide an appropriate response. 33) Suppose you roll a fair, 10-sided die once. The faces on this die are numbered 50, 51, 52, 53,..5.9. (All of the fifties). Calculate the probability that you roll a PRIME NUMBER. A) 3/10 B) 4/10 C) 2/10 D) 1/10 34) For our fair, 10-sided die in the previous problem, if you roll this die TWICE, calculate the probability that you roll a PRIME NUMBER twice. A) 0.16 B) 0.4 C) 0.04 D) 0.09 35) For our fair, 10-sided die in the previous problem, if you roll this die TEN times, let the random variable X represent the number of prime numbers observed out of the 10 trials. X would be considered a random variable. B) poisson A) binomial C) uniform D) geometric A-4

Explanation / Answer

solution:-

33. option C. 2/10

given number 50,51,52,53,54,55,56,57,58,59

from this prime numbers are 53 and 59

so the 2 prime numbers are there = 2 / 10 = 0.2

34. option C 0.04

2 prime numbers are there so 2/10 = 0.2 = (0.2)^2 = 0.04

35. option A. binomial

four fair 10 sided die in the previous problem if you roll this die TEN times let the random variable X represents the number of prime numbers observed out of the 10 trails.X would be considered a BINOMIAL random variable

formula ncr * pr * qn - r
