Question

What is the probability that a student‘s favorite hobby is roller skating ?Theoretical =Experimental =

Answer 1

The theoretical probability is given by 1 over the number of hobbies.

If there is a total of 8 hobbies, the probability of a student having a specific hobby is:

`P=(1)/(8)`

The experimental probability is given by the number of students with that hobby over the total number of students. If 3 students have the hobby roller skating among the 24 students surveyed, the probability is:

`P=(3)/(24)=(1)/(8)`
