Probability

Mr. slacks 6th period class

Definition of probability!

Is the chance that something will happen- how likely it is that some event will happen.

Experimental and Theoretical probability!

Experimental: The chance of something occurring based on an experimental data.

P= #of times events occurred - total # if trials


Theoretical: The chance of something occurring (what should happen in theory)

P= # of possible outcomes - total # of possible outcomes


Some examples of probability!

My question for you!

Probability of marbles!

There are 5 marbles in a bag: 3 are blue, and 2 are red. What is the probability that a blue marble will be picked.

Answer: Number of way it can happen- 3

Total number of outcomes- 5

So the probability is 3/5 - 0.6 as a decimal
