The probability function of a discrete random variable is given as P(X=x)=kx for x=1,2,3,4,5. Eg. P(X=1)=k, P(X=2)=2k. What is the value of P(1<X<4)?

Step 1
So, we can write the equation: k + 2k + 3k + 4k + 5k = 1 15k = 1 k = 1/15 Show more…

The discrete random variable $X$ has probability function given by $$P(x)=\left\{\begin{array}{cc} \left(\frac{1}{4}\right)^{x-1} & x=2,3,4,5,6 \\ k & x=7 \\ 0 & \text { otherwise } \end{array}\right.$$ where $k$ is a constant. Determine the value of $k$ and the expected value of $X .$
