Chapter 0, Problem 55PRT

To determine

To find: the probability of green pencil in the given conditions.

Answer to Problem 55PRT

  $h=5\text{inch}$ .

Explanation of Solution

Given:

The given condition is:

One pencil is randomly selected from 3 red, 4 green, 2 black, and 6 blue pencils.

Concept used:

Probability of the events is given by

  $P\left(E\right)=\frac{\text{Number of possible outcomes}}{\text{Total number of possible outcomes}}$

Calculation:

According to the question, total number of outcomes is $3+4+2+6=15\text{pencils}$ .

number of green pencils is 4 pencil.

Therefore,the probability of green pencil is $P\left(E\right)=\frac{\text{4}}{\text{15}}$

Hence, the probability of green pencil is $P\left(E\right)=\frac{\text{4}}{\text{15}}$ .
