Theoretical Probability

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

• It means the event is certain to occur.

• It means the event is unlikely to occur.

• It means the event will never occur.

• It means the event has an equal chance of occurring or not occurring.

What is Theoretical Probability?

• Theoretical Probability is the likelihood of an event based on past occurrences.

• Theoretical Probability is what should happen in an ideal situation, calculated based on the possible outcomes.

• Theoretical Probability is the probability of an event occurring in real-world scenarios.

• Theoretical Probability is a method used to predict future events based on current data.

What is Experimental Probability?

• Experimental Probability is the theoretical likelihood of an event occurring based on mathematical calculations.

• Experimental Probability is what actually happens when an experiment is conducted, calculated based on the number of times an event occurs divided by the total number of trials.

• Experimental Probability is the probability assigned to an event based on subjective judgment rather than empirical data.

• Experimental Probability is the probability that is determined by the outcomes of previous experiments without conducting new trials.

If a spinner has 6 equal sections, 2 of which are green, what is the theoretical probability of landing on green?

• 1/2

• 1/4

• 1/3

• 2/6

What is the formula for calculating probability?

• Probability = Number of favorable outcomes / Total number of outcomes.

• Probability = Total number of outcomes / Number of favorable outcomes.

• Probability = Number of outcomes / Total possible outcomes.

• Probability = Number of favorable outcomes + Total number of outcomes.

If a spinner is spun 100 times and lands on red 25 times, what is the experimental probability of landing on red?

• 1/2

• 1/3

• 1/4

• 1/5

If a die is rolled, what is the theoretical probability of rolling a 3?

• 1/2

• 1/3

• 1/6

• 1/4

If a bag contains 5 green, 3 red, and 2 blue marbles, what is the theoretical probability of picking a red marble?

• 1/5

• 1/3

• 3/10

• 2/5

What is the probability of an event that is equally likely to happen or not happen?

• 1/4

• 1/3

• 1/2

• 3/4

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

• It means the event is impossible and will not occur.

• It means the event is certain to occur.

• It means the event is likely to occur.

• It means the event has an equal chance of occurring or not occurring.
