Question

Tickets numbered 1 to 20 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn bears a number which is a multiple of 3.

Answer 1

Answer:

Step-by-step explanation:Tickets are numbered,

1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 and 20.

Multiples of 3 between 1 to 20 are 3,6,9,12,15 and 18

Therefore,

There are 6 multiples of 3 between 1 to 20

Therefore,

6/20=2/10
