A random variable X is continuous if possible values or probability density function (pdf) of X is a function f(x) The pdf and probability from Example 4. Write down the probability distribution. Calculate the probabilities for all possible outcomes X = 0,1,2,3,4, and give a representation. 3.6 Using Binomial Tables. tables, I list some of the more useful distributions, both discrete distributions m is 2, ω1 is the probability of no rain, p1 is a degenerate PDF with a value. of the probability distribution function of a standard. Gaussian (μ = 0 and σ = 1). Table A.1 Values of a times the peak value for a Gaussian distribution a z a z a. Some forms of the tables show the probability of Z being less than z, i.e., P(Z

Joint Probability Density Function A joint probability density function for the continuous random variable X and Y, de-noted as fXY(x;y), satis es the following properties: 1. fXY(x;y) 0 for all x, y 2. R 1 1 R 1 1 fXY(x;y) dxdy= 1 3. For any region Rof 2-D space P((X;Y) 2R) = Z Z R fXY(x;y) dxdy For when the r.v.’s are continuous. 16

16 Dec 2012 discrete. P(a ≤ X ≤ b) for all values a and b if the proba- bility distribution is continuous. The probability distribution of a random variable gives 

• The probability p of success is the same for all trials. • The outcomes of different trials are independent. • We are interested in the total number of successes in these n trials. Under the above assumptions, let X be the total number of successes. Then, X is called a binomial random variable, and the probability distribution of X is Statistical Tables for Students Binomial Table 1 Binomial distribution — probability function p x 0.01 0.05 0.10 0.15 0.20 0.25 0.300.35 0.400.45 0.50 Joint Probability Density Function A joint probability density function for the continuous random variable X and Y, de-noted as fXY(x;y), satis es the following properties: 1. fXY(x;y) 0 for all x, y 2.
