Question

Two cards are drawn randomly from a well shuffeled deck of 52 cards with replacement. Find the

probability that selected both cards are of aces.​

Answer 1

Answer:

Total Cards=52.

Total Aces=4.

In first draw: Available cards in sample space is 52.

Probability of drawing an ace is

=4c1/52c1

=4/52

=1/13.

Now before second draw ,previous card is replaced,so available number of cards again in sample space =52.

Probability of drawing an ace

=4c1/52c1

=1/13.

Hence Required probability  

=1/13 × 1/13

=1/169.
