Mutually exclusive event – no common cards together
Overlapping event because a card could be a King and
heart at the same time.
P(Queen or Ace) = P(Queen) + P(Ace)
P(King or Heart) = P(King) + P(heart) – P(King and heart)
Examples:
1.
You choose a card from a standard 52card deck.
Find the probability that you choose a heart or a
spade.
P(heart of spade) =
2.
You choose a card from a standard 52card deck.
Find the probability that you choose an even number
or a heart.
P(even or
heart) =
1.
What is the probability that the ball selected is an odd numbered yellow ball?
2.
What is the probability that a randomly chosen ball is even and red?
3.
What is the probability that a randomly chosen ball is not add and blue?
4.
What is the probability that a randomly chosen ball is odd?

A basket of applies contains 6 red apples, 2 green apples, and 3 yellow apples.
You randomly secto 2 apples, one
at a time.
Find the probability that both are yellow if:
You replace the first apple, then select a second
You eat the first apple, then select the second
Independent Event – you replace the first selection
Dependent Event – your sample space changes, you do
not replace the first outcome.
P(2 yellow apples) =
P(2 yellow apples) =
Example:
An aquarium contains 6 male goldfish and 4 female goldfish.
You randomly select a fish from the
tank, do not replace it, and then randomly choose a second fish.
What is the probability that both fish are
male?
P(male and then female) =
