Suppose a pair of unbiased dice is rolled once if X denotes the total score of two dice write down Sample space

Suppose a pair of unbiased dice is rolled once if X denotes the total score of two dice write down The inverse image of 9

Suppose a pair of unbiased dice is rolled once if X denotes the total score of two dice write down The number of elments in inverse image of X

A six sided die is marked '2' on one face, '3' on two of its faces, and '4' on remaining three faces. The die is thrown twice. If X denotes the total score in two throws, find the values of the random variable and number of points in its inverse images.

An urn contains 2 white balls and 3 red balls . A sample of 3 balls are chosen at random from the urn. If X denotes the number of red balls chosen find the values taken by the random variable X and its number of inverse images .

Suppose two coins are tossed once if X denotes the number of heads Write the sample space

A six sided die is marked 2 on one face 3 on two of its faces and 4 on the remaining faces the die is rolled twice if X denotes the total score in two throws Find the probability mass function

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?

Suppose two coins are tossed once if X denotes the number of heads .find The valuses of the random variable and the number of elements in its inverse image
