Making Predictions Using Probability

Front

What is probability?

Back

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

Front

How do you calculate the expected value in probability?

Back

The expected value is calculated by multiplying each possible outcome by its probability and summing all these products.

Front

What is the probability of selecting a specific color from a set of colored objects?

Back

The probability is calculated by dividing the number of favorable outcomes (specific color) by the total number of outcomes (total objects).

Front

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

Back

The probability of landing on 1 is 1/4 or 0.25.

Front

What is the expected number of times a specific outcome occurs in a series of trials?

Back

The expected number is calculated by multiplying the total number of trials by the probability of the specific outcome.

Front

In a fair coin toss, what is the probability of getting heads?

Back

The probability of getting heads is 1/2 or 0.5.

Front

What does it mean if an event has a probability of 0?

Back

An event with a probability of 0 means that it is impossible for that event to occur.

Front

What does it mean if an event has a probability of 1?

Back

An event with a probability of 1 means that it is certain to occur.

Front

How can you predict the outcome of rolling a number cube (die)?

Back

You can predict the outcome by calculating the probability of each number appearing based on the total number of rolls.

Front

What is the law of large numbers in probability?

Back

The law of large numbers states that as the number of trials increases, the experimental probability will get closer to the theoretical probability.
