1 answer

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

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

From the table, the number of students who want the option to keep studying online is 13. The total number of students is 25.

Now, substituting these values into the formula:

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

Now, to convert this probability into percent form, you can multiply the result by 100:

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

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