Question: Using the PairOfDice class from PP 4.7, design and implement an application that rolls a pair of dice 1000 times, counting the number of box
Using the PairOfDice class from PP 4.7, design and implement an application that rolls a pair of dice 1000 times, counting the number of box cars (two sixes) that occur.

//********************************************************************
public class PairOfDice

I'm just really confused on what to do. Please be descriptive in the response it would be much appreciated. Thank you so much in advance!!
