Please explain and answer correctly!! George flips a colored chip that is red on one side and black on the other a total of 20 times. What is the probability of the 21th flip resulting in landing on the black side up?

The answer is 1/2 because there are two sides and the other 20 flips don't matter for the 21 flip.

Answer:

The chip has no memory so the probability is just 1/2.
