Question

You want to pick a four-player tennis team. There are eight players to choose from. How many

Answer 1

Answer:

70

Step-by-step explanation:

From 8, we want to choose 4.  So:

₈C₄ = 8! / (4! (8-4)!)

₈C₄ = 8! / (4! 4!)

₈C₄ = (8×7×6×5×4×3×2×1) / (4×3×2×1 × 4×3×2×1)

₈C₄ = (8×7×6×5) / (4×3×2×1)

₈C₄ = 70

There are 70 different teams you can form.
