Use the table to answer the question.

Plant Types A B C D E
Number of Seedlings 100 140 80 60 40

A farmer conducted an inventory on his two square kilometers of rainforest; the results are in the table. He plans on randomly selecting a seedling to experiment on when he goes back to the forest. What is the probability that he will randomly pick a type B plant? Write your answer in the simplest form of a fraction.

1 answer

The total number of seedlings is: 100 + 140 + 80 + 60 + 40 = 420

The number of type B seedlings is 140.

Probability of picking a type B plant = Number of type B seedlings / Total number of seedlings
Probability of picking a type B plant = 140 / 420
Probability of picking a type B plant = 1/3

Therefore, the probability that the farmer will randomly pick a type B plant is 1/3.
