Write and solve an equation for the total number of possible combinations from flipping a coin 10 times.
vladimir2022 [97]

Step-by-step explanation:

every flip has 2 possible outcomes.

1 flip has 2.

2 flips have 2×2 = 2² = 4

3 flips have 2×2×2 = 2³ = 8

and so on.

the number of possible combinations flipping a coin n times is

C(n) = 2^n

for 10 flips

C(10) = 2¹⁰ = 1024

possible outcomes or combinations.
