To find the probability of selecting a student who wants the option to keep studying online, we need to divide the number of students who want to continue studying online by the total number of students.

From the table:

  • Total number of students who want the option to keep studying online = 13 (10 girls + 3 boys)
  • Total number of students = 25

The probability (P) can be calculated as follows:

\[ P(\text{wants online option}) = \frac{\text{Number of students wanting online option}}{\text{Total number of students}} = \frac{13}{25} \]

To express this as a percentage, we multiply by 100:

\[ P(\text{wants online option}) \times 100 = \left(\frac{13}{25}\right) \times 100 = 52% \]

Thus, the probability of selecting a student who wants the option to keep studying online is 52%.
