Question

Cards marked with numbers 13, 14, 15, ...., 60 are placed in a box and mixed thoroughly.One card is drawn at random from the box. Find the probability that number on the card drawn is a number is a perfect square

Answer 1

Total no. of possible outcomes = 48 {13, 14, 15, …., 60}

E ⟶ event of getting a perfect square.

No. of favourable outcomes = 4 {16, 25, 36, 49}

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

P(E) = 4/48 = 1/12
