a) Prove algebraically that(m+n | p+n)≥(m | p) for all m, p, n ∈ N and such that m≥p. b) Prove the above inequality by providing a combinatorial proof. Hint: this can be done by creating a story to count the RHS exactly (and explain why that count is correct), and then providing justification as to why the LHS counts a larger number of options. a) Prove algebraically that p for all m, p, n EN, and such that m...
T-1 Suppose two events A and B are mutually exclusive and PAI 0, P[B] 0 . Consider the following statements: i) P(An B)=0 ii) P(A U B) = P(A) + P(B) iii) A and B are statistically independent. Choose the correct statement. A) Only i) is true. B) Only ii) is true. C) Only iii is true. D) Only i) and i) are true. E) i), ii) and iii) are all true.
