Answer 1

Answers:

The probability of not drawing a red marble is 7/10

The probability of drawing a red marble is 3/10

=======================================================

Step-by-step explanation:

We have 3 red marbles out of 5+2+3 = 10 total. Therefore, the probability of selecting a red marble is 3/10.

The probability of not selecting a red marble is 7/10 because 3/10+7/10 = 1. Put another way, we have 7 marbles that aren't red (the 5 blue and 2 black ones) out of 10 total.
