ASSIGNMENT QUESTIONS
NEED TO PROVIDE 4 PROGRAMS AND ANSWER QUESTIONS
1a.    A machine processes two different types of parts.
            The time between arrivals of Type 1 parts is triangularly distributed with a mode of 40 minutes, a minimum of 20 minutes, and a maximum of 50 minutes. TRIA(20,40,50)
            The inter-arrival time of Type 2 parts is from a triangular distribution with a mode of 60 minutes, a minimum of 40 minutes, and a maximum of 70 minutes TRIA(40,60,70).
            Processing time for Type 1 parts is exponentially distributed with a mean of 15 minutes. 
            For Type 2 parts processing time is uniformly distributed with a minimum of 15 minutes and a maximum of 20 minutes. 
            Fifteen percent of the parts are rejected and returned to the en
