To calculate the probability that x is between two values, look at the following graph. Shade the region between x = 2.3 and x = 12.7. Then calculate the shaded area of a rectangle. WebThe cumulative distribution function (cdf) gives the probability as an area. If X is a continuous random variable, the probability density function (pdf), f ( x ), is used to draw the graph of the probability distribution. The total …

WebThe function x ↦ 1 / x is only convex on the domains (0, + ∞) or ( − ∞, 0). Therefore, the inequality E[1 / X] ≥ 1 / E[X] is only valid if P(X > 0) = Add a comment 6 For such a case, it is a good idea to study Jensen's inequality. Another counterexample to the one given by André Nicolas is this one. WebIf the probability of: scoring no goals (Event "A") is 20% scoring exactly 1 goal (Event "B") is 15% Then: The probability of scoring no goals and 1 goal is 0 (Impossible) The probability of scoring no goals or 1 goal is 20% + 15% = 35% Which is written: P (A ∩ B) = 0 P (A ∪ B) = 20% + 15% = 35% Remembering To help you remember, think:
