Tickets are marked from 1 to 20 are mixed up. One ticket is picked at random.

TO FIND: Probability that the ticket bears a multiple of 3

Total number of cards is 20

Cards marked multiple of 3 number are 3,6,9,12,15,18

Total number of cards marked multiple of 3 are 6

`"We know that PROBABILITY" =" Number of favourablr event"/"Total number of event"` 

`"Hence probability of getting a multiple of 3 on the ticket "=6/20=3/10`

`"Hence probability of getting a multiple of 3 on the ticket "3/10`
