Probability Theory

A fair coin is tossed three times and the events A, B, and C are defined as follows:

A:{ At least one head is observed }
B:{ At least two heads are observed }
C:{ The number of heads observed is odd }

Find the following probability by summing the probabilities of the appropriate sample points (note that 0 is an even number):

P((not A) or (not B) or C) =
