A person will label chairs using one letter each. Possible letters are just A, B, C, D. How many unique labels are possible? (Hint: Just count those letters).

You have 4 letters to choose from: A, B, C, and D. When labeling a chair, each letter can be used uniquely. Since each chair can be labeled with any of the 4 letters, the total number of unique labels possible is simply the number of letters available. So, if you label one chair, you have 4 unique labels: A, B, C, and D. If you label two chairs, it'll be 4 options for the first chair multiplied by 4 options for the second chair, giving you 4 × 4 = 16 unique combinations. For n chairs, the unique labels would be calculated as 4^n, where n is the number of chairs, which increases exponentially. Just imagine all the fun combinations you could create for a row of chairs, whether it's for a party, event, or simply organizing your living space!
