What is the definition of Event?

• The result of a single trial in an experiment

• A collection of unrelated outcomes

• A process that cannot be repeated

• A measurement of central tendency

What is the definition of Outcome?

• A possible result of an experiment

• A type of variable in statistics

• A method for collecting data

What is Experimental Probability?

• (number of times an event occurs) ÷ (total number of trials). What ACTUALLY happens when conducting an experiment.

• (total number of trials) ÷ (number of times an event occurs). What is EXPECTED to happen in theory.

• The likelihood of an event based on theoretical outcomes only.

• The ratio of favorable outcomes to possible outcomes in a perfect world.

What is Theoretical Probability?

• (number of favorable outcomes) ÷ (total number of possible outcomes). What SHOULD happen when conducting a probability experiment.

• (number of possible outcomes) ÷ (number of favorable outcomes). What DOES happen when conducting a probability experiment.

• (number of favorable outcomes) × (total number of possible outcomes). What SHOULD happen when conducting a probability experiment.

• (number of favorable outcomes) + (total number of possible outcomes). What DOES happen when conducting a probability experiment.

What is the definition of independent events in probability?

• Two or more events are said to be independent if the occurrence of one event does not affect the probability of occurrence of the other.

• Two or more events are independent if they always occur together.

• Independent events are those that cannot occur at the same time.

• Independent events are those whose probabilities add up to one.

What are complementary events in probability?

• The complement of an event A is the event not A. The sum of complementary events will be one.

• Complementary events are events that can happen at the same time.

• Complementary events are events that have equal probability.

• Complementary events are events that are mutually exclusive but do not cover all outcomes.

What is the joint probability of two independent events A and B?

• The product of the probability of event A and the probability of event B.

• The sum of the probability of event A and the probability of event B.

• The difference between the probability of event A and the probability of event B.

• The ratio of the probability of event A to the probability of event B.
