Question

A box contain cards from 5to 20 A card is drawn from the bag at random find the probability of getting a perfect square

Answer 1

Given n(s) = 16(5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20).

           n(A) = 2(9,16)   ----  perfect squares

P(A) = 2/16

       = 1/8.


Hope this helps!
