In a bag, there are 10 black plastic chips, 7 yellow, 5 red, and 3 green. Two chips are drawn at random with replacement.

Find P(black, then red).

answer choices:

A) 2/25
B) 2/5
C) 3/5
D) 2/3

Answers

When the black chip is drawn, there is already one less chip in the bag; keep this in mind.. the probability of getting a black chip out of the bag is 10/25 or 2/5 now since there is one less chip, there is a total of 24 chips now.. so now the probability of getting a red chip is 5/24  then you would multiply the two events together and get: 2/5 x 5/24....solve
