To find the probability of picking a type B plant, we need to calculate the total number of seedlings and the number of type B seedlings.
Total number of seedlings = 100 + 140 + 80 + 60 + 40 = 420
Number of type B seedlings = 140
Probability of picking a type B plant = Number of type B seedlings / Total number of seedlings
Probability = 140 / 420 = 2/6
Therefore, the probability that the farmer will randomly pick a type B plant is 2/6 or simplifying it, 1/3.
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.
