Question

A bag contains cards which are numbered from 2 to 90. A card is drawn at random from the bag. Find the probability that it bears a number which is a perfect square

Solution

Total no. of possible outcomes = 89 {2, 3, 4, …., 90}

E ⟶ event of getting a no. which is perfect square

No. favourable outcomes = 8 {4, 9, 16, 25, 36, 49, 64, 81}

P(E) =`"No.of favorable outcomes"/"Total no.of possible outcomes"`

P(E) =8/89

  Is there an error in this question or solution?
