Please help with parts a and b:
The probability that a student passes APPDA is 2/3, and the probability that she passes Research Methods is 4/9. If the probability of passing at least one course is 4/5, what is the probability that she will pass both courses ? Final answer in % and 2 decimal places.
A machine consists of two components: A and B. The machine needs both components to operate. As soon as one component breaks the machine fails. The time until component A breaks is an exponential with rate λA = 0.4 per year. The time until component B breaks is an exponential with rate λB = 0.4 per year. The two components are independent. Compute the probability the machine remains functional for at least another 3 years.

- please help me solve both of these questions.arrow_forwardAn analyst estimates there is a probability of 18 percent that there will be a recession next year. He thinks the probability of things being normal is three times the probability of a recession, with the remaining probability assigned to a boom taking place. A stock is expected to return -12 percent in a recession, 10 percent under normal conditions and 24 percent if there is a boom. What is the expected return (in percent) on this stock?

Recall that the expected value is calculated using the formula u = xP(x), where x is the value of a random variable, P(x) is the probability of that variable, and the sum is taken for all values of the random variable. First determine xP(x), the product of x and P(x), for each value of x (let x = 4 for the value of "4 or more"). 1 3 4 or more P(x) 0.46 0.33 0.17 0.03 0.01 1(0.33) 0(0.46) ХP(x) = 0 Submit Skip (you cannot come back).
