Question

Luka has a bag containing 5 socks: 3 red, 1 white, and 1 black. He draws 1 sock out of the bag, replaces it, and then draws another sock.

What is the probability that he will draw a black sock and then a red sock, P(black, then red)?

Answer 1

Me confused

Answer 2

Okay. so what we do is find the probablility of a black sock : 1/5
Since the sock is replaced back then you are still drawing out of 5, Possibility of drawing red is 3/5
So multiply 1/5 and 3/5 and you should get your answer.
