Question

A farmer grows vegetables on seven acres, fruit on six acres, and flowers on two acres. Out in his fields, he finds a ladybug.

To the nearest tenth of a percent, what is the theoretical probability that the ladybug was not found within the acres of flowers?

13.3%
15.4%
84.6%
86.7%

Answer 1

Total acres = 7 + 6 + 2 = 15.
Probability not in flowers = (15 − 2)/15 = 13/15 ≈ 0.866666... = 86.7%.

Answer: 86.7%.
