Question

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.

Answer 1

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

The probability of selecting a type B plant is the number of type B plants divided by the total number of seedlings, which is 140/420 = 1/3.

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