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)
= (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑚𝑢𝑙𝑡𝑖𝑝𝑙𝑒𝑠 𝑜𝑓 5)/(𝑇𝑜𝑡𝑎𝑙 𝑛𝑢𝑚𝑏𝑒𝑟𝑠)
= 8/40
= 𝟏/𝟓
So, the correct answer is (A)
