experimental probability
The chances of something happening, based on repeated testing and observing results. It is the ratio of the number of times an event occurred to the number of times tested. For example, to find the experimental probability of winning a game, one must play the game many times, then divide the number of games won by the total number of games played

Experimental probability:
The chances of something happening, based on repeated testing and observing results. It is the ratio of the number of times an event occurred to the number of times tested. For example, to find the experimental probability of winning a game, one must play the game many times, then divide the number of games won by the total number of games played.
The spinner is divided into 4 sections: 2 blue,1 yellow, and 1 red.
a) The theoretical probability of spinning red is one-half.
b) The experimental probability of spinning blue is three-fifths.
c) The experimental probability of spinning yellow is 100.001%
d) The theoretical probability of spinning red if four-fifths.
Supposedly the correct answer is B, but how?
We can't determine anything about "theoretical" probabilities by
experimentation - that has to be done by analysis of the situation (in
this case, geometric analysis of the spinner and relative sizes of the
blue, yellow, and red sections). So choices (a) and (d) can be
eliminated.
One of the basic axioms of probability says that any probability has
to be between 0 and 1 (0% and 100%) inclusive; it can never be less
than 0 (0%) nor more than 1 (100%). So that eliminates choice (c).
The only one left is (b). Presumably, in order to get that
experimental probability Michael must have landed on blue
(3/5)*20 = 12 times.

finding the probabiliy based on the outcome of an experiment
as opposed to theoretical probability calculated based on the rules

What does your textbook SAY it is?
Looking at some of your recent questions, I would have to ask if you are REALLY sure you want to take a course in Statistics... the questions will get much harder in the very near future.

physical testing of the probability.
Lets say that the probability of getting heads twice in a roll is (1/4) if you flip a coin twice, well you won't know unless you try it for yourself.
