Q. Amari has 8 paint colors available, and he wants to mix 3 of them to create a new color.How many different sets of 3 colors can Amari choose?□
Understand the problem: Understand the problem.Amari has 8 different paint colors and wants to choose 3 of them to mix. We need to find the number of different combinations of 3 colors he can choose from the 8 available colors.
Recognize order doesn't matter: Recognize that the order in which the colors are chosen does not matter.This is a combination problem, not a permutation, because the order of the colors in the mix does not change the outcome.
Use combination formula: Use the combination formula to calculate the number of different sets.The number of ways to choose 3 items from 8 is given by the combination formula: C(n,k)=k!(n−k)!n!, where n is the total number of items to choose from, k is the number of items to choose, "!" denotes factorial, and C(n,k) is the number of combinations.
Plug in values: Plug in the values into the combination formula.Here, n=8 (total colors) and k=3 (colors to choose). So, C(8,3)=3!(8−3)!8!=3!5!8!.
Calculate factorials: Calculate the factorials and simplify the expression.8!=8×7×6×5×4×3×2×13!=3×2×15!=5×4×3×2×1Now, C(8,3)=(3×2×1)×(5×4×3×2×1)8×7×6×5×4×3×2×1
Cancel common terms: Cancel out the common terms in the numerator and the denominator.C(8,3)=3×2×18×7×6
Perform calculation: Perform the calculation.C(8,3)=3×2×18×7×6=68×7×6=8×7=56
Conclude with final answer: Conclude with the final answer.Amari can choose 56 different sets of 3 colors from the 8 available colors.
