Probability of Simple Events

How do you find the probability of NOT choosing a specific outcome?

• Probability of NOT choosing an outcome = Probability of choosing that outcome.

• Probability of NOT choosing an outcome = 1 + Probability of choosing that outcome.

• Probability of NOT choosing an outcome = 1 - Probability of choosing that outcome.

• Probability of NOT choosing an outcome = Probability of choosing that outcome - 1.

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

• It means the event is certain and will definitely occur.

• It means the event is impossible and will never occur.

• It means the event is likely to occur but not guaranteed.

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

What is probability?

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

• A method to predict future events based on past occurrences.

• A statistical tool used to analyze data sets.

• A way to ensure that events will happen with certainty.

What is a simple event in probability?

• An event that consists of multiple outcomes.

• An event that consists of a single outcome.

• An event that cannot occur.

• An event that has a probability of zero.

How do you calculate the probability of a simple event?

• Probability of a simple event = (Number of favorable outcomes) / (Total number of possible outcomes).

• Probability of a simple event = (Total number of possible outcomes) / (Number of favorable outcomes).

• Probability of a simple event = (Number of unfavorable outcomes) / (Total number of possible outcomes).

• Probability of a simple event = (Number of favorable outcomes) + (Total number of possible outcomes).
