Take a dice roll it 20 times and record the numbers you got on its top face.find the mode of resulting numbers.

A pair of fair dice is rolled 2 times. Find the mean of the number of doublets on the dice. Find also variance of the number of doublets on the dice.

Two dice are rolled at same time and the sum of the numbers appearing on them is noted. Find the probability of getting each sum from 3 to 5 separately.

Two dice are thrown at a time and the sum of the numbers on them is 6. The probability of getting the number 4 on any of the dice is

An unbiased coin is tossed. If the result is head, a pair of unbiased dice is rolled and the number obtained by adding the numbers shown on the two faces is noted. If the result is tail, a card from a well shuffled pack of eleven cards numbered 2, 3, 4, ..., 12 is picked and the number on the card is noted. Find the prbability that noted number is either 7 or 8.

Four dice are rolled then the number of possible out comes is

Two dice are thrown at the same time what is the probability that the sum of two numbers appearing on the top of the dice is a prime number.

A die is loaded so that six turns up twice as often as one and three times as often as any other face. Find the probability of getting an even number on the die if the die is rolled once.
