a) Either by using the formula or the binomial chart, fill in the following probability distribution, in which x is the number of times the coin was Heads. 2 3 4 P(x) b) Sketch the histogram for this distribution. c) Note that the graph peaks at x = 3. Why does that make sense – what's special about 3?
