A six faced unbiased dice is rolled 4 times . How many different outcomes are possible?

An unbiased coin is tossed 5 times in succession . How many different outcomes are possible ?

An unbiased dice is rolled one time. Find the probability of occuring 4.

An unbiased coin is tossed. If the result is a head, a pair of unbiased dice is rolled and the number obtained by adding the numbers on two faces is noted. If the result is a tail, a card from a well-shuffled pack of 11 cards numbered 2, 3, 4, ..., 12 is picked and the number on the card is noted. What is the probability that the noted number is either 7 or 8?

How many cyclic C_5H_10 are possible ?

A fair six faced die is rolled 12 times. The probability that each face turns up twice is equal to-

An unbiased coin is tossed . If the outcome is a tail, an unbiased dis is rolled . If the die shows an odd digit, the die is rolled again. Find the sample space associated with this random experiment

An unbiased die is rolled . If it shows an odd face, then we toss an unbiased coin once, if it shows an even face then the unbiased coin is tossed twice. Determine the sample space associated with this random experiment.

How many types of two-dimensional lattices are possible?
