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

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

Suppose two coins are tossed once. If X denotes the number of talls (i) write down the sample space (ii) find the inverse image of 1 (iii) the values of the random variable and number of elements in its inverse images .

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 P(X gt5)

A six sided die is marked 1 on one face 2 on two of its faces and 3 on remaining three faces . The die is rolled twice . If X denotes the total score in two throws .

A six sided die is marked 2 one 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 thross Find P(4 lt x lt 7)

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?
