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 are… 4, 8, 12, 16, 20, 24, 28, 32, …. Number of multiples of 4 less than 15 = 3 Thus, P(getting a multiple of 4) = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ π‘šπ‘’π‘™π‘‘π‘–π‘π‘™π‘’π‘  π‘œπ‘“ 4)/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘›π‘’π‘šπ‘π‘’π‘Ÿπ‘ ) = 3/15 = 𝟏/πŸ“ So, the correct answer is (c)
