To find the probability of selecting a student who wants the option to keep studying online, we can use the formula for probability:

\[ P(\text{want online}) = \frac{\text{Number of students who want online}}{\text{Total number of students}} \]

From the table:

  • The number of students who want the option to keep studying online = 13
  • The total number of students = 25

Now plug in the values:

\[ P(\text{want online}) = \frac{13}{25} \]

Now, to convert this probability into a percentage, we multiply by 100:

\[ P(\text{want online}) = \frac{13}{25} \times 100 = 52% \]

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