For me, the solution is obvious, I must write a function that generates random values, which can be assigned directly to each of the three variables, dice one, dice two and dice three. Here's my solution where I wrote the role function, I pulled a variable r from the main function and stuck the two lines that repeat right in here. R is assigned a value that's generated by the rand function. Module six reduces the value to a range between zero and five, and then r is increased by one so that you have roles one through six. The value of variable r is then returned. In the main function, the…
