Answer -
When a die is thrown, there are total six outcomes, i.e., 1, 2, 3, 4, 5 and 6.
(i)
(a) 2, 3, 5 are the prime numbers. So there are 3 outcomes out of 6.
∴,probability of getting a prime number =3/6 = ½
(b) 1, 4, 6 are not the prime numbers. So there are 3 outcomes out of 6.
∴,probability of getting a prime number =3/6 = ½
(ii)
(c) Only 6 is greater than 5.
So there is one outcome out of 6.
∴,probability of getting a number greater than 5= 1/6
(d) Numbers not greater than 5 are 1, 2, 3, 4 and 5. So there are 5 outcomes out of 6.
∴,probability of not getting a number greater than 5= 5/6
