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 seedlings divided by the total number of seedlings:
140 / 420 = 1/3
Therefore, the probability of randomly selecting a type B plant is 1/3.
A pharma 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 pick randomly type B plant.
