Components 1 and 2 are connected in parallel, so that subsystem works when either 1 or 2 works; since 3 and 4 are connected in series, that subsystem works when both 3 and 4 work. Assume all components work independently of one another, and all components are the same and that P(component works)- 0.9. 3 a) Calculate the probability that either 1 or 2 works, i.e., P(I n2). (8 pt) b) Calculate the probability that both 3 and 4 works, i.e., P (3 U 4). (8 pt) c) Calculate P(system works). (8 pt)

Answer #1

Given that all the components are work independently

a) P(either 1 or 2 works) = 0.9 + 0.9 - P(both work) = 1.8 - (0.9)^2 = 1.8 - 0.81 = 0.99

b) P(both 3 and 4 works) = 0.9*0.9 = 0.81.

c) P(system works) = P(both 3 and 4 works or either 1 or 2 works) = 0.99 + 0.81 - P(1,3,4 works or 2,3,4) = 1.8 - (2*0.9^3) = 0.342

    SHOW ALL WORK! PROBLEM 3.2 (pg 87, #80-see diagrann below) Consider the system of components in the accompanying picture. Components 3 and4 are connected in series (call this subsystem 3-4). Subsystem 3-4 will work only if both components 3 and 4 work. In order for the entire system to function, it must be the case that component 1 functions (Ai) or component 2 functions (A2) or that subsystem 3-4 functions (A34). Suppose that each individual component functions independently of all...

    Problem 4 Consider the system of components connected as depicted below. The system can be thought of as being comprised of two subsystems: one with components A and B, and the other with components C and D. Components A and B are connected in parallel, therefore that subsystem works iff either A or B works. Since C and D are connected in series, that subsystem works iff both C and D work. Components work independent of each other (that is,...

    Please Use your keyboard (Don't use handwriting) Stat (3) One-half percent of the population has CORONA Virus. There is a test to detect CORONA. A positive test result is supposed to mean that you have CORONA but the test is not perfect. For people with CORONA, the test misses the diagnosis 2% of the times. And for the people without CORONA, the test incorrectly tells 3% of them that they have CORONA. (i) What is the probability that a person...
