Question

Two balanced dice are rolled. find the probability that the sum of numbers on two dice is a multiple of 6​

Answer 1

probability = favorable outcomes/possibly outcomes

here,

favourable out comes= 5

possible outcome = 36

probability = 5/36

Answer 2

Possible outcomes

(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)

Probability= no of favourable outcomes / no of all possible outcomes

= 6/36 = 1/6 = 0.16
