Probability helps us guess what might happen by looking at how likely different events are. Here are some important ideas:

1. Basic Probability Formula: To figure out the chance ( P ) of an event happening, we use this formula: $P(A) = \frac{\text{Number of good outcomes}}{\text{Total number of outcomes}}$

2. Example: Imagine you have a bag with 3 red balls and 2 blue balls. So, the total number of balls is 5. To find out the chance of picking a red ball, we do: $P(\text{Red}) = \frac{3}{5} = 0.6 \text{ or } 60\%$

3. Using Probability for Predictions:

   • When you flip a coin, the chance of getting heads is $P(\text{Heads}) = \frac{1}{2} = 50\%$.
   • In games, knowing the chances helps you make better choices and guess what might happen.

When we understand these simple ideas, we can use probability to make smart predictions in many situations.
