For continuous uniform distributions over some range, say from a to b, the sum of the probabilities for the entire range must equal 1 (something in the range must occur), and the probability for a value or event within some segment of the total range is equal to that segment’s ...
Definition of expected value & calculating by hand and in Excel. Step by step. Includes video. Find an expected value for a discrete random variable.
The majority of these people think in a way that is -EV(negative expected value), so most people are getting advice in spots like this from sources who while trying to help them, don’t think in a logical way that will lead to the +EV route(positive expected value). They think in a...

In this work we compute the expected value of the square of the path-difference metric for rooted fully resolved phylogenetic trees under the Yule model. Besides the aforementioned application of this value in the assessment of tree comparisons, the knowledge of formulas for this expected value und...
