Q. 71
In a bag there are 44 identical cards with figure of circles, of which 9 are blue and rest are green and 20 squares of which 11 are blue and rest are green. One card is drawn from the bag at random. Find the probability that it has the figure of (i) square (ii) green colour (iii) blue circle and (iv) green square.
Answer :
Total number of possible outcomes, n(S) = 44
(i) Number of favorable outcomes, n(E) = 20
(ii) Number of favorable outcomes, n(E) = (24 – 9) + (20 – 11) = 24
(iii) Number of favorable outcomes, n(E) = 9
(iv) Number of favorable outcomes, n(E) = 9
