Question 5 The probability that a number selected at random from the numbers 1, 2, 3, ....., 15 is a multiple of 4, is: (a) 4/15 (b) 2/15 (c) 1/5 (d) 1/3 Total numbers = 15 Multiples of 4 areβ¦ 4, 8, 12, 16, 20, 24, 28, 32, β¦. Number of multiples of 4 less than 15 = 3 Thus, P(getting a multiple of 4) = (ππ’ππππ ππ ππ’ππ‘πππππ ππ 4)/(πππ‘ππ ππ’πππππ ) = 3/15 = π/π So, the correct answer is (c)
