Question

What is the probability of rolling a five with two dice?

Answer 1

Is your question about the probability of rolling at least 1 5 with two dice"

If so:

A = rolling 5 with first die

B = rolling 5 with second die

P(A) = 1/6

P(B) = 1/6

P(A or B) = P(A) + P(B) - P(A and B)

= 1/6 + 1/6 - 1/36 = 11/36

If your question is about rolling a 5 twice in a row then:

P(A and B) = P(A) * P(B) = 1/36 (since A and B are independent events)
