A: [At most ONE head is observed]
B: [The number of heads observed is even]
....
1. Identify the sample points of A∪ B
2. Identify the sample points of Ac
3. Identify the sample points in A ∩ B
4. Find the probability of A, B, Ac, A∪ B, and A ∩ B

(1 point) 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 probabilities by summing the probabilities of the appropriate sample points (note that is an even number): (a) P(A)= (b) P(B or (not C))= (c) P((not A) or B or C)=
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...

Suppose that a coin is tossed three times. We assume that a coin is fair, so that the heads and tails are equally likely. Probability that two heads are obtained in three tosses given that at least one head is obtained in three tosses is ___________ Probability that that one head is obtained in three tosses given that at most one head is obtained in three tosses is ____________ at least one means one or more, at most one means...
3. (a) A fair dice is tossed 6 times. Suppose A is the event that the number of occurrences of an even digit equals the number of occurrences of an odd digit, while B is the event that at most three odd digits will occur i. Determine with reason if the events A and B are mutually exclusive. ii. Determine the probabilities of the events A and B. Are the events A and B independent? b) Suppose a fair coin...
