# Experimental vs Theoretical Probability Probability is n A

Experimental vs. Theoretical Probability

Probability is… n A measure of how likely an event is to occur

Theoretical vs. Experimental Probability Theoretical Probability: - The probability we find on paper. - It is how a probability of an event “should” happen. Experimental Probability: - Experimental probability refers to the probability of an event occurring when an experiment was conducted.

Theoretical vs. Experimental Probability Theoretical Probability: number of favorable outcomes Theoretical Probability= number of possible outcomes

Theoretical vs. Experimental Probability: Experimental Probability= number of event occurrences Total number of trials

Theoretical vs. Experimental Probability Example 1: Roll a dice. What is theoretical probability of rolling a 4? # favorable outcomes # possible outcomes 1 6 The probability of rolling a 4 is 1 out of 6

Theoretical vs. Experimental Probability Example 1 Continued: Roll a dice. What is the experimental probability of rolling a 4? # event occurrences Total # of trials

Theoretical vs. Experimental Probability Example 2: Counters. What is theoretical probability of flipping a yellow? # favorable outcomes # possible outcomes 1 2 The probability of flipping a yellow is 1 out of 2 or. 5 or 50%

Theoretical vs. Experimental Probability Example 2 Continued: Counters. What is the experimental probability of flipping a yellow? # favorable outcomes # possible outcomes

Theoretical vs. Experimental Probability Summary: - Theoretical Probability is the how an outcome “should” happen, in theory. - Experimental probability refers to the probability of an event occurring when an experiment was conducted.
