a farmer conducted an inventory on his two square kilometers of rainforset; the results are in the table. he plans on randomly selecting to experiment on when he goes back to the for set. what is the probability that he will randomly pick a type B plant? write your answer in the simplest form of a fraction.
The total number of plants is 100 + 140 + 80 + 60 + 40 = 420.
The number of type B plants is 140.
Probability of picking a type B plant = Number of type B plants / Total number of plants
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.
