What is the difference between experimental and theoretical probability?
Experimental is based on trials, Theoretical is based on theory
Experimental is based on theory, Theoretical is based on trials
There is no difference, they are the same

Anna should have spun C 20% of the time. She actually spun C about 26% of the time. What would you expect to happen to the Experimental Probability Percent if she spun 100 times instead of 30?
Her Experimental Probability should get closer to the TP 20%
She will still spin C about 26% of the time
No way to know! It's just chance!
