Question

Given that the two numbers appearing on throwing two dice are different. Findthe probability of the event ‘the sum of numbers on the dice is 4’.

Answer 1

Answer:

Step-by-step explanation:

S = {(1,2) (1,3) (1,4) (1,5) (1,6)

       (2,1) (2,3) (2,4) (2,5) (2,6)

       (3,1) (3,2) (3,4) (3,5) (3,6)

       (4,1) (4,2) (4,3) (4,5) (4,6)

       (5,1) (5,2) (5,3) (5,4) (5,6)

       (6,1) (6,2) (6,3) (6,4) (6,5)}

P(sum = 4) = 2/30 = 1/15
