- 2P & C Applying symmetryQ: There are 5 chairs. Bob and Rachel want to sit such that Bob is always left to Rachel. How many ways can it be done?
Ans. Because of symmetry, the number of ways that Bob is left to Rachel is exactly 1/2 of all possible ways:
5P2 / 2 - 3PROBABILITY - 1 of n Independent EventsIf occurrence of one event DOES NOT INFLUENCE occurrence of other events.
P (A and B) = P (A) * P (B) - 4PROBABILITY - 2 of n Mutually Exclusive EventsIf events cannot occur at the same time.
P (A or B) = P (A) + P (B) - 5PROBABILITY - n of n Mutually Inclusive EventsConsider this as 2 partially overlapping sets.
P (A or B) = P (A) + P (B) - P (A) * P (B)
