Concept Used:

Numbers multiple of 3: 3, 6, 9, 12, 15, 18

Explanation:

Total numbers of elementary events are = 20

Let E be the event of drawing a multiple of 3

The favourable outcomes are: 3, 6, 9, 12, 15, 18

Total numbers of favourable outcomes are = 6

P (multiple of 3) = P (E) = 6/20 =3/10

Hence, the probability of getting a multiple of 3 is 3/10.
