Theoretical vs Experimental Probability

What type of probability is used to find the probability of an event when all outcomes are equally as likely. "What COULD happen"

• Experimental Probability

• Theoretical Probability

Determine the type of probability:

Damon flipped a coin 50 times and got 31 heads.

Based on the results, the probability of heads is 31/50, or 62%.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

Jane rolled a regular number cube 25 times.

Since she rolled an EVEN number 11 times, the probability of EVEN numbers is 11/25, or 44%.

Determine the type of probability:

The probability of flipping tails is 1/2, or 50%, since the sides of a coin have 1 tails and 1 heads.
