Mark spends one-third of the day sleeping. He spends 8 hours at school and one-sixth of the day at soccer practice. How much free time does Mark have?

4 hours

Step-by-step explanation:

We know that there are 24 hours in a day. Therefore, we will subtract from 24.

If mark spends one-third of his day sleeping, then he will be asleep for 8 hours.

We also know that if Mark spends one-sixth of his day at soccer practice, he will have been practicing for 4 hours.

We now simply subtract from 24:

Therefore, Mark will have 4 hours of free time.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
