79%
32%
18%
82%​

Answer 1

Answer: 82%

Step-by-step explanation: Count the total number of marbles.

9+6+7+11=33 marbles in total.

We are trying to find the probability of NOT picking a blue marble. There are 6 blue marbles. Subtract the blue marbles from the total.

33-6=27

The probability of not picking a blue marble is 27/33. Divide the fraction.

27/33=0.82

Multiply by 100 to get the percent.

0.82 x 100 = 82%

There is an 82% chance of not picking a blue marble.
