Consider the toss of four coins. There are 16 (i. e., 24) possible outcomesin one toss. Assume that all the coins are fair so that for each of them there is50% chance of head and 50% chance of tail.(a)Calculate the probabilities that there is a total number of (1) zero head, (2) one head, (3) two heads, (4) three heads, and (5) four heads appearing on the four coins, respectively.(b)Develop a histogram of the number of heads (one side of the coin) that can appear on any toss. [Hint: the horizontal axis of the histogram is the number of heads.]
