If a standard die is rolled 100 times and the results show that it landed on 1 a certain number of times, how many times would you expect it to land on 1 if rolled 750 times?

Back

105 times; less than theoretically expected

Front

What are the theoretical and experimental probabilities of rolling a number greater than 4 on a standard die?

Back

Theoretical: 1/3 ; Experimental: 9/25

Front

Define theoretical probability.

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes.

Front

Define experimental probability.

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials conducted.

Front

What is the formula for calculating the probability of an event?

Back

P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.
