A fair coin is tossed three times and the events AA, BB, and CC are defined as follows. Find the probabilities of the combined events shown below. It may be helpful to first identify the outcomes that would be in each combined event. {A:{ At least one head is observed } {B:{ At least two heads are observed } {C:{ The number of heads observed is odd } __ a) P(A)= there is a line over a^^ b) P(A∪C) = c) P(A∪B∪C)= there...
