## Question

###### A.b.Let ð‘‹ be a discrete random variable with probability distribution function ð‘“(ð‘¥) = ð‘˜(ð‘¥2 + ðµ) and ð‘‹ = âˆ’1,1,2,3.i. Find the value of ð‘˜. ii. Find the Variance of ð‘‹. Let ð‘‹ denote a discrete random variable which can take the values âˆ’2,0, and 5. Given that the expectation of ð‘‹ is ð‘¨ and ð‘ƒ(ð‘‹ = âˆ’2) = ð‘¨, find ð‘·(ð‘¿ = ðŸ“)
