Chapter 7: Q32. (page 348)

A computer randomly generates an integer from 1 to 10. Find the probability of the given event. Write your answer as a percent.
$P (factor of 20)$

Short Answer

Expert verified

The probability of getting factor of 20 is 50%.

Step by step solution

Step 1. Given Information.

A computer generates an integer from 1 to 10.

Step 2. Formula used.

Probability:

$P = \frac{favorable outcomes}{total outcomes}$

Step 3. Find the probability of getting factor of 20.

To calculate the probability of getting factor of 20, there are 10 total outcomes. It is needed to calculate favorable outcomes.

$\begin{matrix} favourable out comes = \{1, 2, 4, 5, 10\} \\ = 5 \end{matrix}$

Therefore, the probability of getting factor of 20 is obtained as,

$\begin{matrix} P (of gettingfactorof20) = \frac{favorable outcome}{total outcome} \\ P (of gettingfactorof20) = \frac{5}{10} \\ = \frac{1}{2} \end{matrix}$

Therefore, the probability of getting $factor of 20$ is $\frac{1}{2}$ .

Step 4. Convert the obtained fraction form into percent.

Multiply $\frac{1}{2}$ by 100% to convert the fraction form in percent.

$\begin{matrix} P (of gettingfactorof20) = \frac{1}{2} \times 100 % \\ P (of gettingfactorof20) = 50 % \end{matrix}$

Step 5. Conclusion.

The probability of getting $factor of 20$ is 50%.
