Question

You have a bag with 4 pairs of socks. There are 2 red pairs and 2 black pairs. You pull a sock from the bag and put it back 3 times. What is the probability that you pull out a red sock each time?

Answer 1

there are 4 red socks, 4 black socks in the bag

Answer 2

since you keep replacing the red sock, the probability is
4/8 * 4/8 * 4/8

Answer 3

you simply do 1/2 x 1/2 x 1/2

Answer 4

which would be equal to 1/8
