4. (5pts) At MCPHS university, there are three mathematics courses: Algebra (A), Calculus (C), and Statistics (S). Records show that 45% of students take A, 35% take C, 30% take S, 10% take both A and C, 8% take A and S, 5% take C and S, and 3% take A, C, and S. a. Find the probability of those who only take A. b. Find the probability of those who only take one mathematics course. c. Find the probability...

Discrete Mathematics Any degree at a university requires 4 core classes chosen from 4 groups. There are 5 English classes, 3 science classes, 6 math classes, and 4 social studies classes. Students must take exactly one of each class from each group. How many different ways are there for a student to fulfill these requirements?

Suppose that a population consists of the six values 4, 8, 5, 3, 8, and 4. (a) Find the population mean and variance. (b) Calculate the sampling distribution of the mean of a sample of size 3 by displaying all possible such samples (chosen without replacement). (c) Use the results from (b) to find the mean and variance of the sampling distribution. (d) Compare the answers from (c) with those obtained from the general formulas for E(X) and Var(X) derived...
