Assume that time is measured in slot times, and that exactly one slot time is needed to detect a collision (so that if two stations transmit at T=1 and collide, and one of them chooses a backoff time k=0, then that station will transmit again at T=2). Use as coin flip (source of randomness) an ID written in binary. use the bits in order from the least significant to the most significant. If for a given coin throw you need k bits, use the least significant ID bit extracted in the corresponding group of bits, as the least significant bit of the coin thrown.

- Big State University The Big State University course catalog reads as follows: "To enroll in MIS 260, which is an advanced course, a student must complete two prerequisites: MIS 120 and MIS 222. A student who completes either one of these prerequisites and obtains the instructor's permission, however, will be allowed to take MIS 260." Tasks 1. Create a decision table that describes the Big State University course catalog regarding eligibility for MIS 260. Show all possible rules. 2. Simplify the table you just created. Describe the results. 3. Draw a simplified decision tree to represent the Big State University catalog. Describe the results. 4.
