Complementary events in probability are about the chances of something happening or not happening.
Let’s look at a simple example: When we flip a coin, getting heads and getting tails are complementary events. This means if one happens, the other can't.
Understanding Probabilities: These events help us see the bigger picture of probabilities. If you know how likely one event is, you can easily figure out how likely the opposite event is.
Easier Calculations: Instead of figuring out the chances for lots of outcomes, you can often just subtract from 1. For example, if the chance of rain is 0.3 (or 30%), then the chance of no rain is 1 - 0.3, which equals 0.7 (or 70%).
In short, understanding complementary events makes it much easier to work with probabilities!
