Question

Mrs. Trevino has 3 red pens, 5 pink pens, and 8 blue pens. What is the probability that

she will choose a blue pen to grade papers?

Answer 1

Well, If you add them all up (3 + 5 + 8) it will be 16. Now we have to make it a fraction (out of blue pens). That will b 8/16. Now we simplify- 1/2. 1/2 as a percent is 50%. The probability is 50%.
