Find the probability of getting total of 5 or 6 in a single throw of two dice.

Text Solution

Verified by Experts

The correct Answer is:
`(1)/(4)`
Total number of ways is 36. Favorable cases are (1, 4), (2, 3), (3, 2), (4, 1), (1, 5), (2, 4), (3, 3), (4, 2), (5, 1). Total number of favorable cases is 9.
Hence, the required probability is `9//36` = `1//4`.
