Coin tosses can be implemented using the ‘randint (0, 1)’ function from the random module. Be sure to include an import statement. It has the ‘message’ method, which calculates the percentage of heads from the number of tosses and returns a message. Percent of heads Message percent < 0.4 Too few heads 0.4
