["Title: How to Calculate the Total Number of Ways to Choose 4 People from 11: A Detailed Solution", "In combinatorics, one of the most frequently asked questions involves counting combinations — specifically, how to determine the total number of ways to select a group of people from a larger set. In this article, we focus on a fundamental problem: computing the number of ways to choose 4 individuals from a total of 11 people. This foundational calculation lies at the heart of combinatorics and has broad applications in statistics, probability, and everyday decision-making.", "The Problem: Choosing 4 Out of 11 People", "The task is to compute:", "[\n\binom{11}{4}\n]", "That is, how many unique groups of 4 can be formed by selecting members from a pool of 11 distinct individuals? This type of calculation relies on combinations — arrangements where order does not matter.", "### Step 1: Understanding the Formula", "The number of combinations of ( n ) items taken ( k ) at a time is given by the binomial coefficient:", "[\n\binom{n}{k} = \frac{n!}{k!(n-k)!}\n]", "Where:\n- ( n! ) (n factorial) is the product of all positive integers up to ( n ),\n- ( k! ) accounts for the internal order of the selected group,\n- ( (n-k)! ) adjusts for the unselected members.", "### Step 2: Applying the Formula to Our Problem", "Here, ( n = 11 ) and ( k = 4 ).
