Jason rolls a die 14 times.. What is the Experimental probability that he will roll a 1 or 6?

• 1/3

• 1/4

• 3/7

• 1/8

What is the relative frequency of the coin landing on heads?

What is Theoretical Probability?

• The ratio of favorable outcomes to the total number of possible outcomes

• The ratio of favorable outcomes to the total number of trials in an experiment

• In probability, a controlled, repeated process (such as repeatedly tossing a coin).

• A single possible result.

Experimental Probability is:

• What Will happen 

• What actually happens

• What should happen

• What I think Happens

Which of the following describes theoretical probability?

• a. Perform an experiment to determine the probability

• a. Determining the expected probability of an event

• a. Perform a simulation and count the number of possible outcomes

• a. Use trials to count the number of desired outcomes
