4. Let D be the set of weekdays, Monday through Friday, let W be a set of employees {1,2,3} of a tutoring center, and let V be a set of computer languages for which tutoring is offered, {A(PL), B(asic), C(++), J(ava), L(isp), P(ython)}. We define s (schedule) from D into W by dsw if w is scheduled to work on day d. We also define r from W into V by wrl if w can tutor students in language 1. If s and r are defined by matrices 1 2 3 S = = MTWRE 1 0 1 A B C J L P 1 1 0 1 0 0 1 and R - 0 1 1 0 1 0 1 0 1 0 0 1 0 0 1 1 F 1 0 a. compute SR using Boolean arithmetic and give an interpretation of the relation it defines, and b. compute SR using regular arithmetic and give an interpretation of what the result describes. 4.
