Front

What is the expected value in probability?

Back

The expected value is the predicted average outcome of a random event, calculated by multiplying each possible outcome by its probability and summing the results.

Front

If you flip a coin 500 times, how many times should it land on heads?

Back

On average, it should land on heads about 250 times, since there are two possible outcomes (heads or tails) and they are equally likely.

Front

What is the definition of probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

What does it mean if two events are independent?

Back

Two events are independent if the occurrence of one event does not affect the probability of the other event occurring.

Front

How do you calculate the probability of a single event?

Back

The probability of a single event is calculated by dividing the number of favorable outcomes by the total number of possible 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 theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes in a perfect world, while experimental probability is based on actual experiments and observed outcomes.
