So the required probability = 1 -1/2.52 => 0.84 =>at least 84% A die is rolled five times and the number of twos that come up is tallied. Find the probability of getting the indicated result. 3) Two comes up one time. Ans: This is an example of binomial distribution Probability of occurance of 2‚ p = ½ Probability of non-occurrence of 2‚ q = 1-1/2 =1/2 So the probability that two comes 1 times (which means it doesn’t appear on other 4 occaisions) ⇨ C(5‚1) p1q4 ⇨ 5(1/6)(5/6)4
