Consider the density function f x
WebThe joint density function must integrate to 1 over the given domain: ∫∫ fx,y (x, y) dA = ∫0^1 ∫x^1 c (y-x) dy dx = 1 Integrating the inner integral with respect to y gives: ∫0^1 cx (1-x/2) dx = c/6 Explanation: Setting this equal to 1 gives: c = 6 View the full answer Step 2/3 Step 3/3 Final answer Transcribed image text: WebIn the continuous case, f ( x) is instead the height of the curve at X = x, so that the total area under the curve is 1. In the continuous case, it is areas under the curve that define the probabilities. Now, let's first start by …

WebThere are faster methods, but it can be a good idea, at least once or twice, to calculate the cumulative distribution function, and then differentiate to find the density. The upside of doing it that way is that one can retain reasonably good control over what's happening. (There are also a number of downsides!)
WebStatistics and Probability questions and answers. For 0 ≤ x ≤ 1 let f (x) = kx (1 − x), where k is a constant. Find the value of k such that f is a density function and find the cumulative distribution for the previous density function. Do I need to integrate kx (1-x) from 0 to 1 and set it equal to 0 to find k, is that correct?
