theoretical probability is a coin will land on heads 50% of the time

50% of 100 = 50

There are two options so the theoretical probability would be 50% which was different from her experimental probability because that was only 38%. The experimental probability may be different from the theoretical probability as she only spun it 100 times which may not be enough for the probability to work and the experiment may not be fair. She may be spinning it slightly tilted or knocking it or something.
