T or F and explanation

1. A ∩ ∅ = A
2. The number of (ordered) lists of r objects chosen from n is C(n, r)
3. P(n, r) ≥ C(n, r)
4. If A and B are finite sets, then n(A × B) = n(A) × n(B)
5. If A and B are finite sets, then n(A ∩ B) = n(A) + n(B) − n(A ∪ B)

Relations and Functions Usual symbols for the above are; Relations: R1, R2, S, T, etc Functions: f, g, h, etc. But remember a function is a special kind of relation so it might turn out that a Relation, R, is a function, too. Relations To understand the symbolism better, let’s say the domain of a relation, R, is A = { a, b , c} and the Codomain is B = { 1,2,3,4}. Here is the relation: a R 1,    ...

Select true or false - (T/F) A box contains 4 red balls (R) and 3 white balls (W). Sample two balls from the box without replacement. Then P(the 1st ball is R) = P(the 2nd ball is R). - (T/F) Let X be the total number of tosses of a fair coin right before the 2nd tail appears. Then VarX = 4. - (T/F) If (X, Y ) is uniformly distributed over the unit disk {(x, y) ∈ IR2 :...

We denote |S| the number of elements of a set S. (1) Let A and B be two finite sets. Show that if A ∩ B = ∅ then A ∪ B is finite and |A ∪ B| = |A| + |B| . Hint: Given two bijections f : A → N|A| and g : B → N|B| , you may consider for instance the function h : A ∪ B → N|A|+|B| defined as h (a) = f (a)...
