There are 100 cards in a bag on which numbers from 1 to 100 are written. A card is taken out from the bag at random. Find the probability that the number on the selected card (i) is divisible by 9 and is a perfect square (ii) is a prime number greater than 80.

Total No of cards = 100


(i) Numbers divisible by 9 and is a perfect square between 1 and 100 are { 9, 36, 81 }


Total no of favorable outcomes = 3


As




(ii) Prime numbers between 80 and 100 are {83, 89, 93, 97}


Total no of favorable outcomes


As
