Question

which of the following is the probability that a blue marble will NOT be selected from a bag containing 9 red marbles, 6 blue marbles, 7 green marbles, and 11 yellow marbles if one is selected randomly?


18%?


32%?


82%?


79%?

Answer 1

Answer:

82%

Step-by-step explanation:

9+6+7+11=33 total number of marbles

9+7+11=27 marbles that are NOT blue

27/33=9/11 the probability that you will not pick blue

9/11 =0.8181=0.82

Move decimal 2 places to the right for percent

82%

Answer 2

Answer:

82%

Step-by-step explanation:

The total number of marbles is 9 + 6 + 7 + 11 = 33.  6 marbles are blue, so 27 are not.  So the probability of selecting a non-blue marble is 27/33 ≈ 82%.
