4) Consider the (Equally Likely) Experiment of tossing 3 "fair" coins and counting up the number of Tails. Build a Probability Distribution (model) for the Experiment: #Tails: O 2 3 P(#) : 5) For the 3-coin model, find the following: a P(Even number of Tails) b) P(At least 2 Tails) c) P(At most 2 Tails)
