In a simultaneous throw of a pair of dice, find the probability of getting a sum greater than 9
उत्तर
We know that in a single throw of two dices, the total number of possible outcomes is (6 × 6) = 36.
Let S be the sample space.
Then n(S) = 36
Let E5 = event of getting a sum greater than 9
Then E5 = {(4, 6), (5, 5), (5, 6), (6, 4), (6, 5), (6, 6)}
i.e. n (E5) = 6
