A box contains 100 red cards, 200 yellow cards and 50 blue cards. If a card is drawn at random from the box, then find the probability that it will be (i) a blue card (ii) not a yellow card (iii) neither yellow nor a blue card

Total number of possible outcomes, n(S) = 100 + 200 + 50 = 350


(i) Number of favorable outcomes, n(E) = 50



(ii) Number of favorable outcomes, n(E) = 100 + 50 = 150



(iii) Number of favorable outcomes, n(E) = 100
