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!
Wheel of probability!
There are 8 possible outcome!
Dice!
There are one of six outcomes.
Coin Toss Heads and tails!
There are 5 possible outcomes.
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
