HOMEWORK 2 Winter 2016 Due date: Monday February 1 at 4 pm. 1. A data source generates hexadecimal characters. Let X be the integer value corresponding to a hexadecimal character. Suppose that the four binary digits in the character are independent and each is equally likely to be 0 or 1. a) Describe the sample space S (all possible outcomes) of this random experiment and specify the probabilities of its outcomes. b) Show the map from S to the set of values of X . c) Find the probabilities for the various values of X . 2. Two transmitters send messages through bursts of radio signals to an antenna. During each time slot each transmitter sends a message with probability 0.5. Simultaneous transmissions result in loss of the messages. Let X be the number of time slots until the first message gets through. a) Describe the underlying sample space S of this random experiment and specify the probabilities of its outcomes.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
