Tanya and Lauren can choose 2 colors from the 6 available colors (green, orange, yellow, purple, blue, and silver) using the combination formula, which is represented as ( C(n, r) ), where ( n ) is the total number of colors and ( r ) is the number of colors to choose. In this case, ( C(6, 2) = \frac{6!}{2!(6-2)!} = \frac{6 \times 5}{2 \times 1} = 15 ). Therefore, there are 15 different ways for them to choose 2 colors for the soccer uniform.
