Theoretical & Experimental Probability

Front

What is Theoretical Probability?

Back

Theoretical Probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

How do you calculate Theoretical Probability?

Back

Theoretical Probability = (Number of Favorable Outcomes) / (Total Number of Possible Outcomes)

What is Experimental Probability?

Back

Experimental Probability is the likelihood of an event happening based on actual experiments or trials, calculated as the number of times the event occurs divided by the total number of trials.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of Times Event Occurs) / (Total Number of Trials)

What is the Theoretical Probability of rolling a 3 on a 6-sided die?

Back

Theoretical Probability = 1/6, since there is 1 favorable outcome (rolling a 3) out of 6 possible outcomes.

If a bag contains 4 red, 2 blue, and 4 green marbles, what is the Theoretical Probability of drawing a red marble?

Back

Theoretical Probability = 4/10 = 2/5, since there are 4 red marbles out of 10 total marbles.

What is the Theoretical Probability of drawing a green or red marble from a bag with 4 red, 3 green, and 3 blue marbles?

Back

Theoretical Probability = (4 red + 3 green) / 10 total = 7/10.
