Question

Find the probability.

A marble is randomly selected from a bag containing 15 black, 12 white, and 6 clear marbles. Find P(not clear). Round to the nearest percent if necessary.

options:

18%

82%

64%

55%

Answer 1

Answer: 82%

Explanation:

The probability of getting a not clear marble out of the bag is given by the following expression

`P=(not clear marbles)/(all the possibilities)`

The number of not clear marbles in this case, will be the sum of black and white one (15+12=27), and all the possibilities will be the sum of the black, white and clear ones (15+17+6=33). Therefore the probability will be

`P=(not clear marbles)/(all the possibilities)=(27)/(33)=0.8181`

In percentage and rounding to the closest number the probability will be 82%

Answer 2

82%

Explanation:

how i did it was 12 + 15 + 6 is 33 and then 12 + 15 is 27 so it's 27 out of 33. then to find the percentage just divide 27 by 33 and multiply the answer by 100.
