The probability of getting a composite number in a throw of dice is
1/3
The composite numbers among 1, 2, 3, 4, 5 and 6 are 4 and 6. Hence, the number of favourable outcomes is 2 and the total number of outcomes is 6.
Thus, the probability of getting a composite number in a throw of dice = number of favourable outcomestotal number of outcomes = 26 = 13
