Question

You pick a card at random, put it back, and then pick another card at random

Answer 1

Answer:

The probability is 1/9

Step-by-step explanation:

1/3 x 1/3 = 1/9

Answer 2

Answer:  1/9

Reason:

The probability of selecting "7" is 1/3 because there's one card labeled "7" out of three cards total.

The same applies to selecting a "5" as well. When the first card is put back, effectively nothing has changed.

The probability of getting a "7", then getting a "5" is (1/3)*(1/3) = 1/9
