Question

A forest contains about 700 trees. You randomly choose 65 trees and find that 30 of them are pine trees. What is the probability that a randomly selected tree will be a pine tree? Is this probability theoretical or experimental?A. 65/700=9%; experimentalB. 30/65=46%; experimentalC. 30/700=4%; theoretical

Answer 1

Given:

A forest containing about 700 trees.

`\text{Ratio of pine trees is given as }(30)/(65)`
`\begin{gathered} Percentage\text{ of pine trees in the forest=}\frac{\text{30}}{\text{6}5}*100 \\ Percentage\text{ of pine trees in the forest}=46 \end{gathered}`

Probability that a randomly selected tree will be a pine tree is 46%.

It is experimetal.
