Answer 1

B. None of these

Explanation:

There are a total of 12 coins in your pocket.

The probability of drawing a nickel first is 5/12

Since you return the coin, the total number of coins in your pocket doesn't change.

The probability of drawing a dime second is 7/12

Since this is a compound probability problem, multiply the two probabilities together.

5/12 x 7/12 = 35/144

35/144 = 0.243
