On the island of Knights and Knaves we have three people A, B and C. (The island must be known for its inhabitants’ very short names.) A says: We are all knaves. B says: Only one of us is a knave. Using an approach similar to the one in the notes, determine if A, B and C are each a knight or a knave. (The problem might have no solutions, one solution, or many solutions.)

Suppose individuals A, B and C are on a stranded island. There are no other people on the island except for A, B and C. Each of them can only do two activities to survive: either gather coconuts or catch fish. Individual A can either gather 10 coconuts or catch 16 fish; individual B can either gather 8 coconuts or catch 10 fish and individual C can either gather 20 coconuts or catch 20 fish. Assume that all three of...

Three people A, B, and C practice shooting at a target. The probability that A, B, and C hit the target is 0.9, 0.8 and 0.6, respectively. 1) Now select any one of them at random, what is the probability that the person selected hits the target? 2) If the person actually hit target, what is the probability that the person selected is A? 3) If the person selected shoots once more, what is the probability that he hits the...

The following is an Excel Question: We have three factories (A, B, C) and five distributors (P, Q, R, S, T) of our products. The products are shipped by truck from factory to distributor. At most 180 units of our products fit a truck. The shipping cost is $1 per unit to load the truck and $1 per unit to unload the truck plus the mileage cost. The mileage cost is based on the mileage the truck must travel between...

Investigate the following theorems (h) For sets A, B and C we have i. A\(B ∪ C) = (A\B) ∩ (A\C), ii. A\(B ∩ C) = (A\B) ∪ (A\C), iii. A ̸= B if and only if (A\B) ∪ (B\A) ̸= ∅, iv. A ∪ B ⊆ C if and only if A ⊆ C and B ⊆ C. What happens in the extreme case(s) where some (or all) sets are empty?
