Question

a box contains 1 to 100 number cards . randomly one card is drawn what is the probability a prime number and a two digit number​

Answer 1

Answer:

There are 100 cards in the box marked with number 1 to 100.A card is drawn randomly from it.∴ Number of possible outcomes = 100(1)

Let A be the event that the card bears an even prime number.There is only 1 even prime number from 1 to 100, that is '2'.∴ The number of outcomes favourable to A is 1.∴P(A)= 1001
