55. Find the probabilities of the events given in Question 2.

There are 6 outcomes in all (i.e. 1, 2, 3, 4, 5, 6).
(i) Since, there are 3 prime numbers (i.e. 2, 3 and 5)
∴ Favourable outcomes = 3
Thus, probability of getting a prime number =

3 over 6 equals 1 half

(ii) Since, there are 3 non-prime numbers (i.e. 1, 4 and 6)
∴ Favourable outcomes = 3
Thus, the probability of getting a non-prime number =

3 over 6 equals 1 half

(iii) Since, there is 1 number greater than 5 (i.e. 6)
∴ Favourable outcome = 1
Thus, probability of a number greater than 5 =

1 over 6

(iv) Since, there are 5 numbers which are not greater than 5 (i.e., 1, 2, 3, 4 and 5)
∴ Number of favourable outcomes = 5
Thus, the probability of a number which is not greater than 5 =
