Mark spins a penny 100 times and it land head side up 41 times explain why marks experimental probability may be different from the the radical probability of spinning a coin.

Mark's experimental probability may be different from the theoretical probability of spinning a coin because of random chance and sample size. In a smaller sample size like 100 spins, there is a greater likelihood of variation from the expected 50-50 split between heads and tails. This is due to the fact that the probability of landing heads or tails on any given spin is not influenced by the outcomes of previous spins.

Additionally, factors such as the force and angle with which Mark is spinning the coin, the surface on which the coin is landing, and any other external variables can also impact the results of the experiment.

In order to get a more accurate representation of the theoretical probability of spinning a coin, a larger sample size would be needed to reduce the impact of random chance and variability.
