Question

When two dice are rolled, what is the probability of always getting a number on second dice which is less than that of first dice

Answer 1

Hi buddy

Here is your answer

Thus, there are (36−6)/2=30/2=15 out of 36 < signs in the table. Once you've noticed that, it's easy to generalize the result: if you roll two n-sided dice, there are n2 possible outcomes, out of which in (n2−n)/2 the second roll will be less than the first.
