Determine the pmf of y
WebFind the pmf of X given Y = 1. Solution: pX Y=1(1) = p(1,1)/pY (1) = 0.5/0.6 = 5/6 pX Y=1(2) = p(2,1)/pY (1) = 0.1/0.6 = 1/6 2. If X and Y are independent Poisson RVs with respec-tive means λ1 and λ2, find the conditional pmf of X given X + Y = n and the conditional expected value of X given X + Y = n. Solution: Let Z = X + Y. We want to ... WebJun 12, 2010 · Answers and Replies. I think what you've shown is that there is not necessarily a unique solution. As another example consider when X & Y are independent …

WebThe cumulative distribution function (CDF or cdf) of the random variable X has the following definition: F X ( t) = P ( X ≤ t) The cdf is discussed in the text as well as in the notes but I wanted to point out a few things about this function. The cdf is not discussed in detail until section 2.4 but I feel that introducing it earlier is better. WebLet Y be the number on the die. Find the joint pmf of X,Y, and the individual pmf’s of X and Y. Example: Roll a die until we get a 6. Let Y be the number of rolls (including the 6). Let X be the number of 1’s we got before we got 6. Find f X,Y,f X,f Y. It is hard to figure out P(X = x,Y = y) directly. But if we are given the value of Y ...
WebGiven that X = 1, determine the conditional pmf of Y, i.e., py x(0/1), Pyx(11), Pyx (21). b. Given that two hoses are in use at the self-service island, what is the conditional pmf of the number of hoses in use on the full-service island? c. Use the result of part (b) to calculate the conditional probability P(Y < 1 X = 2). d. WebWe have to find the pmf p Y (y) p_Y(y) p Y (y) of the random variable Y = X 2 Y=X^2 Y = X 2.

WebProbability mass function (pmf) and cumulative distribution function (CDF) are two functions that are needed to describe the distribution of a discrete random variable. The cumulative distribution function can be defined as a function that gives the probabilities of a random variable being lesser than or equal to a specific value.
