This question is incomplete buddy, try to ask properly next time. :D
But don't worry I know this question...with solution too.
Qu: A bag contains cards bearing numbers from 11 to 30. A card is taken out from the bag at random. Find the probability that the selected card has multiple of 5 on it.
Sol: No. of cards = 20
Multiples of 5 from 11 to 30 are :
15, 20, 25, 30
So number of favourable outcomes = 4
Required probability = 4/20 = 1/5
