Recall: The sum of all probabilities must be one. Each \(P(x)\) is between zero and one, inclusive. . Suppose also that these values are assumed with probabilities given by P(X x k) f(x k) k 1, 2, . Two percent of the time, he does not attend either practice. a. We discuss probability mass functions and some special ex-pectations, namely, the mean, variance and standard deviation. Cumulative distribution functions Corresponding to any p.d.f f(x), there is a cumulative distribution function, denoted by F(x), which, for any value x∗, gives the probability of the event x ≤ x∗. \(X\) takes on the values 0, 1, 2, 3, 4, 5. . 5 0 obj 0 0 Š Š Š Š Š ÿÿÿÿ � � � 8 Ö ò D � U5 r 6 6 6 6 6 °4 ²4 ²4 ²4 ²4 ²4 ²4 $ Ç6 ² y9 Ô Ö4 9 Š Ö4 Š Š 6 6 Û 5 ¿ ¿ ¿ F Š 6 Š 6 °4 ¿ °4 ¿ ¿ 6 Œ1 à 04 6 ÿÿÿÿ �ö
