Factorial Calculation - Single over Bracketed (Level 1)

This math topic focuses on calculating factorial expressions, specifically those where a single factorial is divided by a factorial with a difference in its argument (symbolized as "n! over (n-r)!"). The problems are designed to test understanding of how factorial calculations interact within the format of division, particularly in scenarios relevant to probability and statistics. Each question presents a factorial divided by another factorial with a subtracted value inside the bracket, challenging students to apply factorial properties and arithmetic operations to find the correct value.
