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?  Choose the correct choice from the following answers:	A) 3/10	B) 1/2	C) 2/5	D) 3/7	E) 1/6
Here, S = {1,2,3,......,19,20}   E= event getting a multiple of 3 = {3,6,9,12,15,18}   probability = 6/20 = 3/10   correct option is 3/10
