For each of the following, use Fitch to give a formal proof of the argument. These look simple but some of them are a bit tricky. Don't forget to first figure out an informal proof. Taut Con and FO Con cannot be used. ∀x (Small(x) → Cube(x)) ∃x ¬Cube(x) → ∃x Small(x) - ∃x Cube(x)

Problem 1. (4 pts) Combinatorics and the Principle of Inclusion Exclusion (a) (2pts) Roll a fair die 10 times. Call a number in 1, 2, 3, 4, 5, 6 a loner if it is rolled exactly once on the 10 rolls. (For example, if the rolls are 1 2 6 4 4 4 6 3 4 1, then 2 and 3 are the only loners) Compute the probability that at least one of numbers 1, 2, 3 is a loner....
