An unbiased die is such that probability of number `n` appearing is proportional to `n^2(n=1,2,3,4,5,6)dot` The die is rolled twice, giving the numbers `aa n db` . Then find the probability that `a

A dice is weighted such that the probability of rolling the face numbered n is proportional to n^(2) (n = 1, 2, 3, 4, 5, 6). The dice is rolled twice, yielding the number a and b. The probability that a gt b is p then the value of [2//p] (where [ . ] represents greatest integer function) is _______.

A biased die is such that probability of obtaining face numbered i is proportional to i . If die is rolled twice and faces a and b turn up on first and second turn respectively, then probability that a is even and b is odd is-
