Answer to Question #97930 in Statistics and Probability for George

Question

What is the probability of obtaining a six at least once in two rolls of a die?

Answer 1

P(obtaining 6 at least once) = 1 - P(no obtaining 6)

P(no obtaining 6 in two rolls) = 5 / 6 * 5 /6 = 25 / 36

P(obtaining 6 at least once) = 1 - 25 / 36 = 11/36

Answer: 11/36
