I toss a fair coin 20 times.

(a) Calculate the probability of tossing 18 or more heads exactly.

(b) Now perform the same calculation, approximating the actual binomial distribution with a normal distribution, picking a proper random variable, and using the correct mean and variance. (c) Do the results reasonably agree?

Suppose you toss a fair coin 10 times. (a) Calculate the probability of getting at least 6 heads, using the exact distribution. (b) Now repeat the calculate above, but approximate the probability using a normal random variable. Do your calculation both with and without the histogram correction. Which one is closer to the true answer? Now suppose you toss a fair coin 1000 times. (c) What is the probability of getting at least 520 heads? You can approximate this using...

Write an application that simulates coin tossing. Let the program toss a coin each time the user chooses the “Toss Coin” menu option. Count the number times each side of the coin appears. Display the results. The program should call a method flip( ) that takes no arguments and returns a zero to represent a tail or a one to represent a head. There is a Random class that will allow you to generate a random integer. Import it from...
