Question

Three dice are rolled simultaneously. What is the probability that exactly two of the dice will come up as the same number?

Answer 1

In each case the different number may show on any of the three dice, so there is a total of six ways to make the throw. The total number of ways the dice can fall is 6x6x6, so the probability of making the throw is6/216, or 1 in 36. First, the statement that two of the dice must be the same is totally irrelevant.

Answer 2

Answer:

90/216 ways =5/12

Step-by-step explanation:

1-p(different no.s)-p(same numbers)

1-(5/9)-(1/36)

1-21/36

5/12
