The document discusses probability and provides examples to illustrate the difference between theoretical and experimental probability. It notes that theoretical probability is calculated based on what should happen, while experimental probability is determined by actual results of an experiment. It then gives several examples of calculating both theoretical and experimental probabilities for events like spinning numbers on a spinner, rolling dice, and drawing cards from a deck.

Inv. #7:
REMEMBER....
*Theoretical Probability is:
What "should" happen and what we use for calculating
probability in class
*Experimental Probability is:
Found by actually conducting an experiment or collecting data

Examples:
A) A spinner for a game is divided into 8 equal sections numbered 1
through 8. What is the probability of spinning a prime number?
B) You toss a coin 100 times. Predict the number of times it will land
on tails.
