Two standard 6-sided dice are rolled. What is the probability that the sum rolled is a perfect square?
The possible numbers when two dice are rolled is 2 - 12, inclusive
Of these, only 4 and 9 are perfect squares
The probability that 4 is rolled is 3/36
The probabilty tht a 9 is rolled is 4/36
So P(4 or 9) =
3/36 + 4/36 =
7/36
