If necessary, round your answer to 2 decimal places.

Answer 1

3/10 is the Probability of not Drawing Blue Marbles

Explanation:

Blue Marbles = 7

Green Marbles = 2

Red Marbles = 1

Total Marbles = 7 + 2 + 1 = 10

Probaility of Drawing Blue Marbles = 7 /10

Probability of not Drawing Blue Marbles = 1 - Probaility of Drawing Blue Marbles

= 1 - 7/10

= 3/10

or

Probability of not Drawing Blue Marbles = Probability of drawing Green or Red Marbles

= 2/10 + 1/10

= 3/10
