Explanation Given info: The table shows the results from the ‘Carbon Monoxide test for smoking’, in which 49 smokers have positive test results, 24 non-smokers have positive test results, 57 smokers have negative test results and 370 non-smokers have negative test results. Calculation: The total number of subjects for ‘Carbon Monoxide test for smoking’ is obtained as shown in the Table (1). Positive test result Negative test result Total Smoker 49 57 106 Nonsmoker 24 370 394 Total 73 427 500 Table (1) Let event A denote the subject with a negative test result and the event B be denoted as the subject is a nonsmoker. Probability : The formula for probability of the event A is, P ( A ) = Number of ways event A occurs Number of simple events Substitute 427 for ‘Number of ways of event A occurs’ and 500 for ‘Number of simple events’ P ( A ) = 427 500 = 0

T1.4: Let ẞ(G) be the minimum size of a vertex cover, a(G) be the maximum size of an independent set and m(G) = |E(G)|. (i) Prove that if G is triangle free (no induced K3) then m(G) ≤ a(G)B(G). Hints - The neighborhood of a vertex in a triangle free graph must be independent; all edges have at least one end in a vertex cover. (ii) Show that all graphs of order n ≥ 3 and size m> [n2/4] contain a triangle. Hints - you may need to use either elementary calculus or the arithmetic-geometric mean inequality.

We consider the one-period model studied in class as an example. Namely, we assumethat the current stock price is S0 = 10. At time T, the stock has either moved up toSt = 12 (with probability p = 0.6) or down towards St = 8 (with probability 1−p = 0.4).We consider a call option on this stock with maturity T and strike price K = 10. Theinterest rate on the money market is zero.As in class, we assume that you, as a customer, are willing to buy the call option on100 shares of stock for $120. The investor, who sold you the option, can adopt one of thefollowing strategies: Strategy 1: (seen in class) Buy 50 shares of stock and borrow $380. Strategy 2: Buy 55 shares of stock and borrow $430. Strategy 3: Buy 60 shares of stock and borrow $480. Strategy 4: Buy 40 shares of stock and borrow $280.(a) For each of strategies 2-4, describe the value of the investor’s portfolio at time 0,and at time T for each possible movement of the stock.(b) For each of strategies 2-4, does the investor have…
