Design an FA (Finite automaton) and RE to accept the set of all strings over the alphabet {0,1} which contains even number of 0's and odd number of 1's.

Recall that the set {0,1}∗ is the set of all finite-length binary strings. Let f:{0,1}∗→{0,1}∗ to be f(x1x2…xk)=x2x3…xkx1. That is, f takes the first bit of a string x and moves it to the end of x, so for example a string 100becomes 001; if |x|≤1, then f(x)=x Also, suppose that g:{0,1}∗→{0,1}∗ is a function such that g(x1…xk)=0x1…xk (that is, gg puts an extra 0 in front of the given string, so for example g(100)=0100. Everywhere in this question we...

Prove that a disjoint union of any finite set and any countably infinite set is countably infinite. Proof: Suppose A is any finite set, B is any countably infinite set, and A and B are disjoint. By definition of disjoint, A ∩ B = ∅ In case A = ∅, then A ∪ B = B, which is countably infinite by hypothesis. Now suppose A ≠ ∅. Then there is a positive integer m so that A has m elements...

Let P be a partial order on a finite set X. Prove that there exists a linear order L on X such that P ⊆ L. (Hint: Use the proof of the Hasse Diagram Theorem.) Do not use induction

Using only membership tables (i.e., without Venn diagrams or set identities), prove or disprove that (? − ?) ∪ (? − ?) and ((? − ?̅) − ?) ∪ (? ∩ ?̅) ∪ (? − (? ∪ ?)) are equivalent. Ensure that you fill the table completely, even if you are disproving this equivalence, and do not skip any columns.
