How do you calculate the probability of an event?

• Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

• Probability = (Total number of possible outcomes) / (Number of unfavorable outcomes)

• Probability = (Number of outcomes) / (Total number of events)

• Probability = (Number of favorable outcomes) + (Total number of possible outcomes)

What is theoretical probability?

• The likelihood of an event occurring based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of outcomes.

• The probability of an event based on past occurrences and historical data.

• The chance of an event happening in a specific situation without considering all possible outcomes.

• The probability that is determined by personal judgment rather than mathematical calculation.

What does it mean if the probability of an event is 0?

• It means the event is impossible and cannot 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.
