Chapter 12.3, Problem 38S

To determine

To calculate the probability to draw orange chips from the bowl

Answer to Problem 38S

The probability to get orange chips is 36%

Explanation of Solution

Given information:

Number of red chips a bowl contain is 3

Number of green chips a bowl contain is 6

Number of yellow chips a bowl contain is 5

Number of orange chips a bowl contain is 8

Formula used:

Probability = $\frac{\text{Number of favorable outcomes}}{\text{Number of possible outcomes}}$

Calculation:

Total number of chips in a bowl = $3+6+5+8=22$

Probability to draw orange chips from the bowl is calculated as,

  $\begin{array}{l}\text{P}\left(\text{orange chips}\right)=\frac{\text{Number of orange chips}}{\text{Total number of chips}}\times 100\%\\ \text{P}\left(\text{orange chips}\right)=\frac{8}{22}\times 100\%\\ \text{P}\left(\text{orange chips}\right)=0.36\times 100\%\\ \text{P}\left(\text{orange chips}\right)=36\%\end{array}$

Therefore, the probability to get orange chips is 36%
