15.2.63 One Dimensional Random Variables and Their Characteristics
Condition: The density of the distribution of the random value \ (f (x) = \ frac {a} {1+x^{2}} \). Find: \ (a, f (x), m [x] \), \ (d [x], p \ {0 \ leq x \ leq 1 \} \), draw the graph \ (f (x) \ (x) \)
Study of Discrete and Continous One-Dimensional Random Variaans, Calculation of Their Characteristics Such as Mathematical Expectation, Standard Deviation, Standard Deviation, Moments, Distribution and Density Functions. WE ALSO Consider Problems on Known Distributions - Gauss, Bernoulli, Poisson. Finding The Probabilites of Various Events, Including Those from Evedey Life.
