Fundamental Counting Principle
Master Fundamental Counting Principle in Grade 10 math. Suppose items are to be chosen. If there are ways to choose the first item, ways to choose the secon.
Key Concepts
Suppose $k$ items are to be chosen. If there are $n 1$ ways to choose the first item, $n 2$ ways to choose the second item, and so on, then there are $n 1 \cdot n 2 \cdot \ldots \cdot n k$ ways to choose all $k$ items.
Create a 2 character password using letters (A Z) where letters can be repeated: $26 \cdot 26 = 676$ possible passwords. An ice cream shop has 10 flavors and 4 types of toppings. The number of single scoop, single topping options is $10 \cdot 4 = 40$. A student has 5 shirts and 3 pairs of pants. The number of different outfits is $5 \cdot 3 = 15$.
Common Questions
What is Fundamental Counting Principle?
Suppose items are to be chosen. If there are ways to choose the first item, ways to choose the second item, and so on, then there are ways to choose all items. The Fundamental Counting Principle is a fancy name for a simple idea: if you have to make a series of choices, you just multiply the...

Why is Fundamental Counting Principle important for Grade 10 students?
Ever tried to solve a mystery with two clues? The elimination method is just like that for math! It helps you find the values of two variables (like x and y) in a system of equations by cleverly getting rid of one variable first. It's a powerful way to make a complex problem much simpler. Here’s...
