Which оf the fоllоwing аre the three types of muscle tissue?

Prоblem 1: Set Operаtiоns аnd Prоbаbility Rules (25 pts, 5 pts each) a) (bigcup_{n=2}^infty (n^{-n},1) = ?) b) (bigcup_{n=1}^{infty} (-frac{1}{n},frac{1}{n}) = ?) c) (Omega = {1,2,3,4}). Let (A = {1,2,4}) and (B={2,3}). If all events are equally likely, find (P(A cap B^c)). d) (Omega = {1,2,3,4}). Let (P(Omegasetminus{3}) = x) and (P({4}) = y). What is (P({3}))? e) (Omega = {1,2,3,4}). Let (P(Omegasetminus{3}) = x) and (P({4}) = y). What is (P({1,2}))? Problem 2: Bayes' Theorem (25 pts) A hospital uses a diagnostic test to screen patients for a rare disease. We use (D) as a random variable indicating if the patient actually has the disease ((D=1)) or is healthy ((D=0)). The binary random variable (T) indicates if the test is positive ((T=1)) or negative ((T=0)). The test correctly identifies 80% of the patients who have the disease, (P(T=1|D=1) = 0.8). The test incorrectly gives a positive result for 5% of healthy patients, (P(T=1|D=0) = 0.05). Please answer the following questions about this diagnostic test. a) If 5% of the population has this disease, what is the probability a patient with a positive test result actually has this disease? In other words, what is (P(D=1|T=1))? b) Say the test is improved, so now (P(T=1|D=1) = 0.01). If 5% of the population has this disease, what is the probability a patient with a positive test result actually has this disease? c) This disease is even more rare in some populations. Using the original test, what is the probability that a patient with a positive test result actually has this disease if the base rate of the disease is 1%? Problem 3: Joint and Marginal PMFs (25 pts) Roll a four-sided dice twice. Let (X) be the number of dice that show values greater than or equal to three. Let (Y) be the number of dice that are odd. a) Find the joint PMF of (X) and (Y). b) Find the marginal PMF of (X). Problem 4: Expectations of a Known Random Variable (25 pts) Let (X sim text{Geometric}(p)) with (p = 1/2). a) Evaluate (mathbb{E}[p^X]). b) Evaluate (P(X < 1/p)). Hint: Remember that (P(X in mathcal{A}) = mathbb{E}[mathbb{1}[X in mathcal{A}]]). Congratulations, you are almost done with Midterm 1.
