Answer: 1/2
In decimal form this is 0.5 and it converts to 50%
===================================================
Step-by-step explanation:
Assuming the coin is a fair coin, meaning that each side is equally likely to be landed on, this means the probability of flipping heads is 1/2 = 0.5 = 50%
This is true of any flip. The coin doesn't have memory of previous events, so past events do not affect its probability. Each event is independent of any other.
