7.6E Simple Events & Complimentary Probabilities

Front

What is a simple event in probability?

Back

A simple event is an event that consists of a single outcome.

Front

Define complementary events in probability.

Back

Complementary events are two outcomes of an event that are mutually exclusive and together cover all possible outcomes.

Front

If the probability of an event A is 0.7, what is the probability of its complementary event A'?

Back

The probability of the complementary event A' is 0.3 (1 - 0.7).

Front

What is the formula to find the probability of complementary events?

Back

P(A') = 1 - P(A), where P(A') is the probability of the complementary event.

Back

The probability is 1/6.

Front

What are the possible outcomes when flipping a coin?

Back

The possible outcomes are heads and tails.

Front

If the probability of event B is 0.4, what is the probability of not B?

Back

The probability of not B is 0.6 (1 - 0.4).

Front

Explain the difference between independent and dependent events.

Back

Independent events do not affect each other's outcomes, while dependent events do.
