Expected value calculator continuous function
WebThe expected value of X is 2 3 as is found here: We'll leave it to you to show, not surprisingly, that the expected value of Y is also 2 3. Definition. The continuous random variables X and Y are independent if and only if the joint p.d.f. of X and Y factors into the product of their marginal p.d.f.s, namely:

WebStep 1: Find the height of the distribution.The area under a probability distribution is always 1.As there are 30 units (from zero to 30), then the height is 1/30. Step 2: Find the width of the “slice” of the distribution mentioned in the question.Do this by subtracting the biggest number (b) from the smallest (a), to get b – a = 15 – 10 = 5. mike o\\u0027hearn youngWebJan 7, 2024 · Learn how to calculate the Mean, a.k.a Expected Value, of a continuous random variable.
