MUTUALLY EXCLUSIVE EVENTS
• Events are mutually exclusive if they can not happen at the
same time.
NOT MUTUALLY EXCLUSIVE
EXAMPLES
• What is the probability of rolling a 2 or a 5 on a 6 sided
die?
• What is the probability of rolling a 4 or a multiple of 2?
EXAMPLE
• You choose a card from a standard deck of cards. What is
the probability of drawing a 10 or a face card?
• What is the probability of drawing a face card or a spade?
COMPLIMENTS
• The complement of an event consists of all the possible
outcomes that are not part of the event.
• For example, the probability of not drawing a face card from a
deck of cards.
• Since total probability is 1, the probability of a complement is
• 1 – P(event)
EXAMPLE
You roll two dice. What is the probability of not rolling
doubles?
What is the probability of rolling 10 or less?
