To find the probability of randomly selecting a type B plant, we need to first calculate the total number of type B plants in the rainforest.
Looking at the table, we see that there are 140 type B plants in the 2 square kilometers of rainforest.
Next, we find the total number of all plants in the rainforest:
400 (type A) + 240 (type B) + 160 (type C) = 800 plants total
The probability of randomly selecting a type B plant is then:
Number of type B plants / Total number of plants
= 140 / 800
= 7 / 40
Therefore, the probability of randomly selecting a type B plant is 7/40.
a farmer conducted an inventory on his 2 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 they he will randomly pick a type B plant? Write your answer in the simplest form of a fraction.
