What is the probability of selecting a student who wants the option to keep studying online? Write your answer in percent form.

Answer 1

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

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

From the table provided, the number of students who want to keep studying online is 13 (10 girls and 3 boys).

The total number of students is 25 (15 girls and 10 boys).

Now, we can calculate the probability:

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

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

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

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