Distribution 4907
A continuous random variable X is specified: distribution function, specify the parameters a; b so that the function F (x) is continuous and was the distribution function of the random variable X and express f(x).
P (X <5)
F (x) = 0; x <3
F (x) = a. x - b; 3
F (x) = 1; 6> x
P (X <5)
F (x) = 0; x <3
F (x) = a. x - b; 3
