To find the probability of a student (either boy or girl) wanting the option to continue studying online, we can use the formula for probability:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
In this case:
- The number of students who want the option to study online is \(13\) (10 girls + 3 boys).
- The total number of students is \(25\) (15 girls + 10 boys).
Now, applying the values to the formula:
\[ \text{Probability} = \frac{13}{25} \]
To convert this into a percentage, we multiply by \(100\):
\[ \text{Probability in percent} = \left(\frac{13}{25}\right) \times 100 = 52% \]
So, the probability of a randomly selected student wanting the option to continue studying online is 52%.
