Type the correct answer in each box. If necessary, use / for the fraction bar. A bag contains 5 blue marbles, 2 black marbles, and 3 red marbles. A marble is randomly drawn from the bag. The probability of not drawing a black marble is? The probability of drawing a red marble is?

P (not drawing a black marble) = 4/5

P (red marble) = 3/10

Step-by-step explanation:

The total number of marbles is

5 blue marbles + 2 black marbles + 3 red marbles = 10 marbles

P (not drawing a black marble) =

The marbles that are not black / total marbles

(blue + red) / total

(5+3) / 10

8/10

4/5

P (red marble) = red marble / total

= 3/10
