Two dice are thrown together. What is the probability that the sum of the numbers on the two faces si neither divisible by 3 nor by 4?

Explanation

P(sum of faces neither divisible by `3` nor by `4`)

`Sum = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}`

Sum neither divisible by `3` nor `4 = {2, 5, 7, 10, 11}`

P(sum of faces neither divisible by `3` nor by `4`)` = 5/11`
Hence, probability is `5/11`
