Experimental vs Theoretical Probabilities
ormation
The table below shows the results of an
experiment in which the spinner above was
spun 60 times. Find each probability based
on the experiment and compare to the
theoretical probability.

Blank 1 is for number 1, blank 2 for number 2, etc.
1. P(4)
2. P(a number less than 10)
3. P(a prime number)
4. Theoretically, if the spinner is spun 150 times, how many times would
expect to get an even number?
5. Based on the experiment, if the spinner is spun 150 times, how many
