Mutually Exclusive Events

Front

What are mutually exclusive events?

Back

Events that cannot occur at the same time. For example, rolling an odd number and rolling an even number on a die.

If the probability of an event A is 0.28 and the probability of event B is 0.55, how do you find the probability of event C (not A or B)?

Back

Use the formula: P(C) = 1 - (P(A) + P(B)). In this case, P(C) = 1 - (0.28 + 0.55) = 0.17.

What is the formula for calculating the probability of an event?

Back

P(Event) = \frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ outcomes}.

Front

If two events A and B are mutually exclusive, what is the probability of A or B occurring?

Back

P(A or B) = P(A) + P(B).

What is the total number of outcomes when rolling a six-sided die?

Back

There are 6 possible outcomes: {1, 2, 3, 4, 5, 6}.

If the probability of winning a game is 0.4, what is the probability of losing?

Back

The probability of losing is 1 - 0.4 = 0.6.

Front

What does it mean if two events are not mutually exclusive?

Back

It means that both events can occur at the same time. For example, drawing a card that is red and a card that is a heart.
