Texts: A new test for COVID-19 has been developed. It gives either a positive or a negative result. Experiments have been carried out on the usefulness of this test, on people known to have COVID-19 and people known not to have COVID-19. The results of these experiments were: - If the tested person has COVID-19, there is a 0.90 probability that the test will be positive. - If the tested person does not have COVID-19, there is a 0.95 probability that the test will be negative. Suppose that 8% of the people to be tested do, in fact, have COVID-19. (i) Work out the probability that a randomly selected person will test positive. [2 marks] (ii) Suppose that a randomly selected person tests positive. Work out the probability that he or she actually has COVID-19. [4 marks] (iii) Suppose that a randomly selected person tests negative. Work out the probability that he or she actually has COVID-19.

A solid aluminum [$E = 74 \text{ GPa}$] rod (1) is connected to a solid bronze [$E = 95 \text{ GPa}$] rod (2) at flange B, as shown. Aluminum rod (1) has an outside diameter of 39 mm and bronze rod (2) has an outside diameter of 19 mm. The normal stress in the aluminum rod must be limited to 123 MPa, and the normal stress in the bronze rod must be limited to 92 MPa. Assume $L_1 = 161 \text{ mm}$ and $L_2 = 310 \text{ mm}$. Determine: (a) the maximum downward load $P$ that may be applied at flange B. (b) the deflection $v_B$ (downward is positive) of flange B at the load determined in part (a).
