Discrete random variable X has possible values 2, 6, 10, 14, 18, and 22. Continuous random variable Y has density function f(y) = y/288, if 0 < y < 24 and f(y) = 0 otherwise. If Y is a good approximation for X, find Pr[6 ≤ X ≤ 18].1/41/35/72/31
Let X be a discrete random variable whose value is given by the number of successes observed on a series of 10 Bernoulli trials in which the probability of success is 1/3. Which of the following statements is or are true? I. X = B(10, 1/3) II. The only possible values of X are the integers 1 through 10 inclusive. III. If Y=10 - X, then Y = B(10, 2/3). A. I only B. I and II only C. I...
2. For a discrete random variable X, with CDF F(X), it is possible to show that P(a < X S b)-F(b) - F(a), for a 3 b. This is a useful fact for finding the probabil- ity that a random variable falls within a certain range. In particular, let X be a random variable with pmf p( 2 tor c-1,2 a. Find the CDF of X b. Find P(X X 5). c. Find P(X> 4). 3. Let X be a...
