Problem
A bag contains only blue and green marbles. The total number of marbles in the bag is 60, and the probability of drawing a blue marble in one random draw is 53.
(i) Define the terms “sample space” and “event” for this experiment.
(ii) If the number of blue marbles is b, express the probability of drawing a blue marble in terms of b.
(iii) Hence determine the values of b and the number of green marbles in the bag.
