Probability permutation proof

WebbThis formula says that we can multiply the probabilities of two events, but we need to take the first event into account when considering the probability of the second event. If the events are independent, one happening doesn't impact the probability of the other, and in that case, P (\text {B} \text {A})=P (\text {B}) P (B∣A) = P (B).

For n people sitting on k chairs, the number of possibilities is equal to n* (n-1)* (n-2)*...1 divided by the number of extra ways if we had enough people per chair.
