1. Warm up: write the equation of the line described
Passing through (3, -1) Passing through (6, 4) and
and (-5, 7) Perpendicular to y=-3x+4

2. Probability part duex
11.2

3. Or means add!!!

4. Mutually exclusive events
Events are mutually exclusive if they can not happen at the same time.

5. Not mutually exclusive

6. 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?

7. 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?

8. 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)

9. example
You roll two dice. What is the probability of not rolling doubles? What is the probability of rolling 10 or less?
