To find the chance of something happening, there’s an easy formula to use. It’s all about comparing the number of good outcomes to all the possible outcomes. Here’s the formula:

$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

Let’s break it down:

• $P(E)$ means the chance of the event happening.
• Favorable outcomes are the ones that match what you want.
• Total outcomes are everything that could happen in that situation.

For example, imagine you’re rolling a die and you want to know the chance of rolling a 4.

In this case, you have:

• 1 favorable outcome (rolling a 4)
• 6 total possible outcomes (which are 1, 2, 3, 4, 5, and 6).

So the chance of rolling a 4 would be:

$P(4) = \frac{1}{6}$

It’s pretty straightforward, right? Just make sure to count carefully!
