Let a, b, c, and d be the numbers that show when four fair dice, numbered 1 through 6 are rolled. The probability that `|(a – 1) (b − 2)(c – 3) (d – 6)] = 1`
(A) 6/324
(B) 4/324
(C) 3/324
(D) 1/324

A number is selected from numbers 1 to 25. The probability that it is prime 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 dice is rolled.The probability of getting an even prime is (1)/(6) (b) (1)/(3)(1)/(2)(d)(5)/(6)

A die is thrown once.The probability of getting a prime number is (2)/(3)(b)(1)/(3)(c)(1)/(2) (d) (1)/(6)

Let a red die,a blue die,a green die and a white die are rolled once,the dice being fair. The outcomes on the red,blue,green and white die denote the numbers,a,b,cand respectively.Let E denote the event that absolute value of (a-1)(b-2)(c-3)(d-6)=1, then P(E) is (A) (1)/(324) (B) (1)/(648) (C) (2)/(324) (D) (1)/(162)

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

If two different dice are rolled together,the probability of getting an even number on both dice,is (1)/(36) (b) (1)/(2)( c) (1)/(6) (d) (1)/(4)

A fair coin is tossed. If head appears, a fair dice is tossed once and the number on the upper face noted. If tail appears, the fair dice is tossed twice independently and the sum on the upper faces is noted. Then the probability that the noted number is 3, is (A)1/18 (B)1/4 (C)1/6 (D)1/9

A six-faced fair dice is shown until 1 comes. Then the probability that 1 comes in even number of trials is (a) (1)/(6) (b) (1)/(36) (d) (1)/(18) (d) (3)/(28)

If matrix A= [(1, 2, 3),( 2, 3, 1),( 3, 1, 2)] then |adjA| is: (A) 18 (B) -18 (C) 324 (D) -324
