). Suppose a group of users share a 1 Mbps link. Each user requires 100 Kbps when transmitting, but each user transmits only 20% of the time. a. (10 points) When circuit switching is used, how many users can be supported? b. (15 points) Suppose packet-switching is used. If there are 50 users, use the binomial distribution to compute the probability that more than 10 of the 50 users are transmitting simultaneously at any given time. (Hint: You can write a program to compute this probability.)

Consider the following statements: #include #include class temporary { private: string description; double first; double second; public: temporary(string = "", double = 0.0, double = 0.0); void set(string, double, double); double manipulate(); void get(string& , double& , double& ); void setdescription(string); void setfirst(double); void setsecond(double); }; write the definition of the member function set() so that the instance variables are set according to the parameters. write the definition of the constructor so that it initializes the instance variables using the function set() write the definition of the member function manipulate() that returns a decimal number (double) as follows: if the value of description is "rectangle", it returns first * second if the value of description is "circle" it returns the area of a circle with radius first if the value of description is "cylinder" it returns the volume of a cylinder with radius first and height second. hint: the volume of a cylinder is simply the area of the circle at the base times the height. if the value of description is "sphere" it returns the volume of the sphere with radius first. otherwise it returns -1.0;
