Open Ended

What is the value of the possibality of an event occurring ?

Probability of Simple Events

Sample Size

Sample size is all the possible outcomes.

Coin

The sample size of a coin is:

Head and Tail

Six Sided Dice

The sample size of a six sided dice is 1 2 3 4 5 & 6

Spinner

The sample size of this spinner is Green Blue Orange and Red

Experimental probability is what actually does happen after you have performed the experiment
