Example 8 A box contains 3 blue, 2 white, and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it will be (i) white? Total number of marbles = 3 + 2 + 4 = 9 Number of marbles which are white = 2 P(marble taken out is white) = ( )/( ) = 2/9 Example 8 A box contains 3 blue, 2 white, and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it will be (ii) blue? Total number of marbles = 9 Number of marbles which are blue = 3 P(marble taken out is blue) = ( )/( ) = 3/9 = 1/3 Example 8 A box contains 3 blue, 2 white, and 4 red marbles. If a marble is drawn at random from the box, what is the probability that it will be (iii) red? Total number of marbles = 9 Number of marbles which are red = 4 P(marble taken out is red) = ( )/( ) = 4/9
