How many ways can you choose 3 posters from 24 posters?

Answer 1

To find the number of ways to choose 3 posters from 24, you can use the combination formula, which is given by ( C(n, r) = \frac{n!}{r!(n - r)!} ). Here, ( n = 24 ) and ( r = 3 ). Plugging in the values, we get ( C(24, 3) = \frac{24!}{3!(24 - 3)!} = \frac{24 \times 23 \times 22}{3 \times 2 \times 1} = 2024 ). Thus, there are 2024 ways to choose 3 posters from 24.
