Expected value calculator continuous function
WebAn important property of the expected value, known as transformation theorem, allows us to easily compute the expected value of a function of a random variable. Let be a random variable. Let be a real function. … Webnicefella. 1,029 3 16 33. 13. Joint probability density functions do not have expected values; random variables do. A very useful result called the law of the unconscious statistician says that if Y = g ( X), then the expected value of Y can be found from the distribution of X via. E [ Y] = ∫ − ∞ ∞ g ( x) f X ( x) d x,

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.
