Cards numbered from 11 to 60 are kept in a box. If a card is drawn at random from the box, find the probability that the number on the drawn cards is
(i) an odd number
(ii) a perfect square number
(iii) divisible by 5
(iv) a prime number less than 20
Total number of possible outcomes, n(S) = 50
(i) Number of favorable outcomes, n(E) = 25
(ii) Number of favorable outcomes, n(E) = 4
(iii) Number of favorable outcomes, n(E) = 10
(iv) Number of favorable outcomes, n(E) = 4
