What is the difference between independent and dependent events?

• Independent events are those that do not affect each other's probabilities, while dependent events do.

What is the formula for calculating probability?

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

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

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

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