Best answer
(i) with replace: there are 52 cards out of which 4 are queens ∴ Probability of getting a queen = \(\frac{4}{52}\) The card is replaced before the second draw. Again a card is drawn, getting a queen in the second draw = \(\frac{4}{52}\) ∴ Probability of getting two queens = \(\frac{4}{52}\)x \(\frac{4}{52}\)= \(\frac{1}{169}\) (ii) without replacement: when one card is not replaced there are 51 cards for the second draw with 3 queens. ∴ Probability of getting queen in second draw = \(\frac{3}{51}\) ∴ P(both queens) = Queen in 1st draw x queen in second draw \(=\frac{4}{52} \times \frac{3}{51} = \frac{12}{2625}\)
