Determine in which of the following situations a binomial distribution can be applied. If so, state and graph the distribution of X, and find the mean and standard deviation of X. If not, state which of the four conditions to satisfy the binomial distribution requirements has been violated.

The worksheets cover concepts in probability and help students practice skills like listing sample spaces, possible values of random variables, and solving probability problems. The document contains worksheets on discrete probability distributions, mean, variance, and expectation.

Find the range of the following random variables. Flip a coin once; ! X = 1 (H), 0 (T) Flip a coin 5 times; ! X = #heads. Toss two dice; ! X = sum, Y = absolute value of di↵erence. Select four numbers from 1:20 at random, without replacement; ! X = maximum of the 4 numbers. Toss a coin repeatedly until a head first appears.

Construct a probability distribution of the random variable X, where X is the number of persons in a randomly selected family. We need to be familiar with three types of random variables. We’ll look at an example of each: Let X be a random variable denoting the number of heads observed in 6 flips of a coin.

Random Variables and Distribution Functions Worksheet 9 1. Choose two number at random from f1;2;3;4;5g. Let X be rst value and and Y be the second. (a) Make a table for the joint mass function f X;Y (x;y) (b) Find the mass function for Z = X + Y. (c) Simulate 10000 samples of Z. With these simulations, use the table command to see how well

Which of the following are discrete random variables? The heights of students in a Year 12 class. The weights, to the nearest kg, of students in a Year 12 class. The number of runs scored in a cricket test match in Brisbane in 2002. The number of consecutive heads obtained when repeatedly tossing a coin.
