Experimental and Theoretical probability

Front

What is Experimental Probability?

Back

Experimental Probability is what actually happens in an experiment, calculated as the number of times an event occurs divided by the total number of trials.

Front

How do you calculate Experimental Probability?

Back

Experimental Probability = (Number of times the event occurs) / (Total number of trials)

Front

If a die is rolled 5 times and lands on 3 three times, what is the experimental probability of rolling a 3?

Back

P(3) = 3/5

Front

What is Theoretical Probability?

Back

Theoretical Probability is what should happen in an experiment based on all possible outcomes.

Front

How do you calculate Theoretical Probability?

Back

Theoretical Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

Front

If a die has 6 sides, what is the theoretical probability of rolling a 2?

Back

P(2) = 1/6

Front

What is the experimental probability of a coin landing on heads if it is tossed 10 times and lands on heads 6 times?

Back

P(Heads) = 6/10 = 3/5

Front

If a spinner has 4 equal sections numbered 1 to 4, what is the theoretical probability of landing on 3?

Back

P(3) = 1/4

Front

What is the experimental probability of rolling a 4 if a die is rolled 12 times and lands on 4 four times?

Back

P(4) = 4/12 = 1/3

Front

If a coin is tossed 20 times and lands on tails 8 times, what is the experimental probability of landing on tails?

Back

P(Tails) = 8/20 = 2/5
