Question

There are 15 tickets in a box, each bearing one of the numbers from 1 to 15. One ticket is drawn at random from the box. Find the probability of event that the ticket drawn -
(1) shows an even number.
(2) shows a number which is a multiple of 5.

Answer 1

Answer:

7/15 - showing even number

1/5 - showing a multiple of 5

Step-by-step explanation:

Total tickets = 15

Tickets with even number = 7     ( 2 , 4 , 6 , 8 , 10 , 12 , 14)

Tickets multiple of 5 = 3      ( 5 , 10 , 15)

Probability of showing even number = 7/15

Probability of showing a number multiple of 5 =  3/15 = 1/5
