6.18 Dice Simulation It is often useful to be able to simulate the throw of a fair die. Write a MATLAB function dice that simulates the throw of a fair die by returning some random integer between 1 and 6 every time that it is called. Hint: Call randomO to generate a random number. Divide the possible values out of randomO into six equal intervals, and return the number of the interval that a given random value falls into.)
