You are watching: Which of the following is the best definition of probability

. <19 points> express to trouble 1. (a) find the accumulation distribution role F(x). Be certain to compose your thedesigningfairy.com in the approp


Step-by-step explanation:

a) We know that the cummulative distribution function of a continous random variable X is identified as:




hence that cdf will certainly be

\limits^x_0 \\\\F(x)=-\fracx^225 +\frac25x" alt="F(x)=\int\limits^x_0 (-\frac225t + \frac25 )\, dt\\\\=\frac25<-\fract^210 + t>\limits^x_0 \\\\F(x)=-\fracx^225 +\frac25x" align="absmiddle" class="latex-formula">

b) median of X is offered as:


c) For second moment
