Question

4 faced dice, 6 faced dice, Probability that when rolled same number appears on both of them

Answer 1

Hi Nupur,

 

Since there are 4 different possibilities that can happen on the first die and 6 different possibilities on the second, the probability of a 1 showing on the first die and a 1 showing on the second die is  (1/4)(1/6) = 1/24. If a 2 shows on the first and a 2 on the second the probability is again (1/4)(1/6) = 1/24. The probability of the dice matching on a 3 or 4 will have the same probabilities. Therefore the probability of the two dice matching is 

 

                               4(1/4)(1/6) = 1/6
