Webb7 feb. 2024 · The possible values for X are 1, 2, 3, 4, 5, and 6, all equally likely and each having the probability of . The expectation of X is given by: A probability experiment is something that has an uncertain result. In the context of probability, this is often just referred to as an experiment. An outcome is a possible result of an experiment. WebbAs we can see from Graphical Tests for Normality and Symmetry, the skewness is SKEW (A4:A23) = .23 (cell D13) with standard error SQRT (6/COUNT (A4:A23)) = .55 (cell D16). Since .23 < 2*.55 = 1.10, the skewness is acceptable for a normal distribution.
