Question

A bag has 7 red marbles, 8 blue marbles, and 5 purple marbles, Rachel draws a marble from the bad without looking.What is the probability that Rachael draw a blue marbleA. 4%B.8%C.12%D.40%E.66.7%

Answer 1

To find the probability of drawing a blue marble we have to divide the number of blue marbles and the total number of marbles. There are 8 blue marbles, and there are 20 total marbles.

`P_{\text{blue}}=(8)/(20)=(2)/(5)=0.4`

Hence, the probability is 40%.
