Question

15 cards, numbered 1, 2, 3 ......., 15are put in a box mixed thoroughly. a card is drawn at random from the box. find the probability that the card drawn bears an even number and divisible by 2 or 3

Answer 1

Probability of even no.is=
no.of observation/total outcomes =
7/15

P(divisible by 2or 3 )=10/15==2/3

Answer 2

Total events = 15
even number from 1 to 15 that are divisible by 2 or 3= 2,4,6,8,10,12,14=7 numbers
p(even numbers divisible by 2 or 3) =7/15

Hope this helps you!!!
