Question 16 One ticket is drawn at random from a bag containing tickets numbered 1 to 40. The probability that the selected ticket has a number which is a multiple of 5 is (A) 1/5 (B) 3/5 (C) 4/5 (D) 1/3 Total number of tickets = 40 Multiples of 5 less than or equal to 40 are… 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, … Number of multiples of 5 less than or equal to 40 = 8 Thus, P(getting a multiple of 5) = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ π‘šπ‘’π‘™π‘‘π‘–π‘π‘™π‘’π‘  π‘œπ‘“ 5)/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘›π‘’π‘šπ‘π‘’π‘Ÿπ‘ ) = 8/40 = 𝟏/πŸ“ So, the correct answer is (A)
