Chapter 12.7, Problem 33PPE

To determine

To find: The number of trees in the park that are likely to be oak trees.

Answer to Problem 33PPE

The total number of oak trees is likely around $201$ .

Explanation of Solution

Given:

The total trees in the park are 500 and 27 out of 67 are randomly chosen

Calculation:

The objective is to determine the value of $P\left(\text{trade}\text{school}\text{or}\text{community}\text{college}\right)$ .

The experimental probability is conducted with certain number of trial then the experimental probability is,

  $P=\frac{\text{number}\text{of}\text{favorable}\text{outcomes}}{\text{number}\text{of}\text{times}\text{experiment}\text{is}\text{done}}$

Since, the 27 out of $67$ randomly chosen than,

  $P=\frac{27}{67}$

Then, the experimental probability when the total trees in the park are 500 is,

  $\begin{array}{c}P=\frac{27}{67}\times 500\\ =201\end{array}$
