Given that two different dice are tossed.

Total number of outcomes = 6²

= 36.

(1) Let A be the event of getting a doublet.

n(A) = {1,1},{2,2},{3,3},{4,4},{5,5},{6,6}

= 6.

Required probability P(A) = 6/36

= 1/6.

(ii) Let B be the event of getting a sum of 10 of the numbers of two dice.

n(B) = {6,4},{4,6},{5,5}

= 3.

Required probability P(B) = n(B)/n(S)

= 3/36

= 1/12
