1. Write a program to simulate an experiment rolling two six-sided “fair” dice. Allow the user to enter the number of rolls of the dice to simulate. What percentage of the time does the sum of the dots on the dice equal 8 in the simulation? 2. A convenient approximation for computing the factorial n! for large values of n is given by the Stirling formula:

Water Salinity modifications 1. 2 Modify the program so that it converts and prints the new temperature in degrees Centigrade. 3.Suppose that the data used with the program contained values with the degrees in Centigrade. Would the program need to be changed? Explain. It does not need to be changed since the equation is same. 4. Open Jet 1. 2. 3.
