Two different dice are tossed together. Find the probability that (i) the number on each die is even, (ii) the sum of the numbers appearing on two dice is 5.

Total numbers of elementary events are: 6 x 6 = 36

(i) Let E be the event of getting an even number on each die


The favourable combinations are: (2, 2), (2, 4), (2, 6), (4, 2), (4, 4), (4, 6), (6, 2), (6, 4), (6, 6)


Then, the number of favourable outcomes are = 9


P (getting even number on both dice) =P (E) = 9/36 = 1/4


(ii) Let E be the event of getting the sum of the numbers appearing on two dice is 5


The favourable combinations for event are: (1, 4), (2, 3), (3, 2), (4, 1)


Then, the numbers of favourable combinations = 4


P (sum of numbers appearing on two dice is 5) =P (E) = 4/36 = 1/9
