In: Statistics and Probability
Consider an experiment in which three different coins (say a penny, a nickel, and a dime in that order) are tossed and the sequence of heads and tails observed. For each of the following pairs of events, A and B, give the subset of outcomes that defines the events and state whether the pair of events are mutually exclusive, collectively exhaustive, neither or both. (a) A: The penny comes up heads. (b) A: The penny comes up heads. B: The penny comes up tails. B: The dime comes up tails. (c) A: At least one of the coins shows heads. B: At least one of the coins shows tails. (d) A: There is exactly one head showing. B: There is exactly one tail showing. (e) A: Two or more heads occur. B: Two or more tails occur.
