Probability

What I know about it: probability- probability is how probable (likely) you are to get something, or how probable you are to not get something (unlikely).
If something is certain that means that is the only thing that you can pick. Also if something is impossible that means you can not pick that thing because that thing is not in the bag.

I know that in probability that you use theoretical probability and experimental probability. Theoretical probability is what you expect or predict will happen. Experimental probability is when you test your theory by doing an experiment and figuring out if it was close to your theoretical probability. Also in probability you usually use fractions. Probability is a part to whole situation. The numerator would be the outcomes out of the denominator (all the possible outcomes)

If a probability problem has "and" in it you have to multiply the probabilities. ALWAYS.

If the problem has "or" in it you have to add the two probabilities together.
