A reading list for a course contains 20 articles How many ways are there to choose three articles from this list?
To choose three articles from a list of 20, you can use the combination formula, which is given by ( C(n, r) = \frac{n!}{r!(n-r)!} ). Here, ( n = 20 ) and ( r = 3 ). So the number of ways to choose three articles is ( C(20, 3) = \frac{20!}{3!(20-3)!} = \frac{20 \times 19 \times 18}{3 \times 2 \times 1} = 1140 ). Thus, there are 1,140 ways to choose three articles from the list.
