Unformatted text preview: Y is zero, what are x 1 , x 2 , and x 3 ? (ii) Create a plot of x 2 vs Y for Y from 0 to 10 (iii) Within this interval, what value of Y minimizes x 2 ? What is the minimum value of x 2 ? 2/. (4 marks) The diagram below illustrates the states that an individual can be in during a flu epidemic, the possible state transitions, and the probabilities that an individual who is in state i will transition to state j in a day . What is the probability that an individual will be healthy (i.e. in state S0)? What is the probability that an individual will be in isolation (i.e. in state S3)? S1: Infected S0: Healthy S2: Infected with treatment S3: Infected in isolation R(1,0) = 1/6 R(2,1) = 1/2 R(3,2) = 1/5 R(0,1) = 1/8 R(1,2) = 1/2 R(2,3) = 1/4...
