Let X represent the number of heads subtracts the number of tails obtained when a coin is tossed 3 times, i.e., X = number of heads − number of tails.
(a) Find the probability mass function of X
(b) Given that X is at least 0, what is the probability that X is at least 2

Heads or Tails Create a JavaFX application that simulates a coin being tossed. When the user clicks a button, the application should generate a random number in the range of 0 to 1. If the number is 0, the coin has landed on “heads,” and if the number is 1, the coin has landed on “tails.” Use an ImageView component, and the coin images that you will find in this book’s Student Sample Programs to display the side of the...
