1. (5 pts). A coin is flipped 4 times.
Greeley [361]

Answer:

4/8 or 1/2

Step-by-step explanation:

there are 2 sides of the coin and we flipped it 4 times so 2 x 4 = 8

there are 8 possible outcomes

only 1 side of the coin is face up and we flipped it 4 times so 1 x 4 = 4

so there is a 4/8 (or 1/2 if you want to simplify) chance of flipping a coin four times and landing face up each time.
