Question

A jar contains 7 red jelly beans, 2 black jelly beans and 6 green jelly beans. You draw ONE jelly bean. What is the probability of drawing a red bean?

Answer 1

7 + 2 + 6 = 15

Now out of these 15 only 7 are red.


Probability is normally written as a fraction.

7/15

We can also convert this number to a percentage.

7/15 doesn't turn into a percentage evenly and must be rounded to:

47%
