Making decisions every day often means thinking about chances. The Addition and Multiplication Rules can help us understand these chances better:
Addition Rule: This rule is helpful when we have different options to choose from.
For example, if I want to find out the chance of picking either a red marble or a blue marble from a bag, I would add the chances together.
So, it looks like this: [ P(A) + P(B) ]
Multiplication Rule: This rule is used when two events do not affect each other.
Let's say I'm tossing two coins. To find the chance of getting heads on both coins, I would multiply the chances.
Here’s how it works: [ P(heads) \times P(heads) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} ]
Using these rules makes it easier to see our choices and what might happen in everyday situations!
