You randomly draw a marble from a bag of marbles that contains 7 blue marbles, 2 green marbles, and 1 red marble.

What is P? (not draw a blue marble)

If necessary, round your answer to 2 decimal places.

Procedure:

7 blue + 2 green + 1 red = 10

the answer for not drawing a blue one would be 3/10

or 30% or 0.3 because 2 + 1 = 3 and we have already eliminated the seven blue ones. So we have a 30% of drawing a green or red marble.
