1.	There are 100 cards in a bag on which numbers from 1 to 100 are writtacard is taken out from the bag at random. Find the prohability thnumber on the selected card 6) is divisible by 9 and is a perfect(ii) is a prime number greater than 80.
Answer» (i) Total cards =100 The numbers those are divisible by 9 and are perfect squares are 9, 36, 81. Therefore probability that the number on the selected card is divisible by 9 and is a perfect square is 3/ 100 (ii) Total cards =100 The prime numbers greater than 80 are, 83, 89, 97 Therefore probability that the number on the selected card is a prime number greater than 100 is 3 ./100

Answer»

(i) Total cards =100 The numbers those are divisible by 9 and are perfect squares are 9, 36, 81.

Therefore probability that the number on the selected card is divisible by 9 and is a perfect square is 3/ 100

(ii) Total cards =100 The prime numbers greater than 80 are, 83, 89, 97

Therefore probability that the number on the selected card is a prime number greater than 100 is 3 ./100
