Four fair dice D_(1),D_(2),D_(2) and D_(4) each having six faces numbered 1, 2, 3, 4, 5 and 6 are rolled simultaneously. The probability that shows a number appearing on one of D_(1),D_(2) and D_(2) is:

Two dice are rolled simultaneously. The probability that they show different faces is 2/3 (b) 1/6 (c) 1/3 (d) 5/6

Two dice are rolled simultaneously.The probability that they show different faces is (2)/(3) (b) (1)/(6)(c)(1)/(3)(d)(5)/(6)

A die is rolled, then the probability that a number 1 or 6 may appear is a. 2/3 b. /6 c. 1/3 d. 1/2

A die is rolled, then the probability that a number 1 or 6 may appear is a. 2/3 b. 1/6 c. 1/3 d. 1/2
