P(X=x) =k *(x^2+ 1)If this is a probability mass function, where X can only take on values of 1, 2, 3, and 4. Determine the value of k.
Added by Damon W.
Step 1
A PMF must satisfy two conditions: (1) P(X=x) ≥ 0 for all x, and (2) the sum of all probabilities P(X=x) for all possible x values must equal 1. Show more…

2. Let X be a discrete random variable with the following PMF PX(k) = { 0.5 for k = 1; 0.3 for k = 2; a for k = 3; 0 otherwise } (a) Find the value a so that PX(k) is a valid PMF. (b) If Y =2/X, find EY.
