Question

Derek is selecting a sock from his drawer .He chooses a sock at random and then selects a second sock at random .what is the probability that Derek selected a striped sock both times

Answer 1

Answer: 1/15

Explanation:

The number of striped socks is 2 while the number of total socks are 6. If he chooses a striped socks at first, that will be 2/6.

If he chooses it the second time, the probability will be 1/5 since there'll be 5 socks left and 1 striped.

The probability that Derek selected a striped sock both times will be:

= 2/6 × 1/5.

= 2/30

= 1/15
