4. Generalize the Bayesian analysis of medical screening given in class. Let a rare disease D occur with probability P(D)-δ, with δ small. The test for this disease is accurate such that the W1 probability of a correct result is 1-e, with ε small. Derive formulas for the probabilities of a true positive P(D +) and a false positive, P(p+). For this screening to be useful...

5. In each step, explain clearly what property or axiom you are using. (a) Prove "inclusion-exclusion," that PAU B)-P(A)+P(B)-Pan B) (b) Prove the "union bound" that P(Ai UA2) P(Ai) P(A2). Under what conditions does the equality hold? (c) Prove that, for A and A2 disjoint, P(A UA2 B) P(A B)P(A2 B) (d) A and B are independent events with nonzero probability. Prove whether...

2. A device consists of two redundant subunits; only one needs to be working for the device to function. The first subunit has two parts Wi and W2, and the second has two parts W3 and W4. In each subunit, both parts must function for the subunit to work. The four parts are independent identical and equally reliable, with probability p- 0.9 of functioning. (a) What...

Let A, B and C be three events defined on a sample space S (for the purposes of illustration assume they are not disjoint as shown on the Venn diagram below). Find expressions and draw the Venn diagram for the event, so that amongst A, B and C: a. only A occurs b. both A and B occur, but not C c. all three events occur d. none of the events occurs e. exactly one of the events occurs f....

Please clear answer and if you can avoid hand writing. Thanks ahead. An unknown triprotic acid (so “n” = 3) sample of mass 0.225 g required 38.22 mL of 0.09767 M NaOH to neutralize where 2.14 mL of 0.1015 M HCl was used to back titrate, find the molar mass of the unknown solid acid in grams per mole.
