Question

A jar contains 13 red, 27 blue, and 20 green marbles. if one marble is drawn from the jar at random, find the probability that the marble is: red, blue, not blue, green, green or red​

Answer 1

The probability that a marble drawn from the jar at random is red is 21.66%, that it is blue is 45%, that it is not blue is 55%, that it is green is 33.33%, and that it is green or red is 55%.

Explanation:

Since a jar contains 13 red, 27 blue, and 20 green marbles, to determine, if one marble is drawn from the jar at random, the probability that the marble is red, blue, not blue, green, and green or red, you must perform the following calculations:

13 + 27 + 20 = 60

Red = 13/60 = 0.2166

Blue = 27/60 = 0.45

Not blue = 33/60 = 0.55

Green = 20/60 = 0.333

Green or red = 33/60 = 0.55

Therefore, the probability that a marble drawn from the jar at random is red is 21.66%, that it is blue is 45%, that it is not blue is 55%, that it is green is 33.33%, and that it is green or red is 55%.
