Chapter 7: Q31. (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.
$P (even number)$

Short Answer

Expert verified

The probability of getting even number 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 even number.

To calculate the probability of getting even number, there are 10 total outcomes. It is needed to calculate favourable outcomes.

$\begin{array}{l} favourable outcomes = \{2, 4, 6, 8, 10\} \\ = 5 \end{array}$

Therefore, the probability of getting even number is obtained as,

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

Therefore, the probability of getting even number 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.

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

Step 5. Conclusion.

The probability of getting even number is 50%.
