🎯 Key Concepts
🪙 What Is Probability?
Probability measures how likely an event is to occur.
🎲 Experimental Probability
🎲 Experimental Probability
Found by performing an experiment and observing outcomes.
🎯 Theoretical Probability
As the number of trials increases, experimental probability gets closer to the theoretical probability.
🧩 The Fundamental Counting Principle (FCP)
🧩 The Fundamental Counting Principle (FCP)
If an event has m ways to occur and another event has n ways,
then together they have m × n possible outcomes.
Example 1:
If you can wear 2 shirts (blue, red) and 3 pants (black, khaki, gray):
2×3=6 possible outfits.
Example 2:
You roll a die (6 outcomes) and flip a coin (2 outcomes):
6×2=12 total outcomes.
