3/10 is the Probability of not Drawing Blue Marbles  

Step-by-step 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

3/10 is the Probability of not Drawing Blue Marbles
