Description: A random variable X takes values 0, 1, 2, 3 with probabilities 2a+1/30, 8a-1/30, 4a+1/30,b respectively, where a, b \in R. Let µ and σ respectively be the mean and standard deviation of X such that σ^2 + µ^2 = 2. Then 1/b is equal to: | Watch the step-by-step video solution for this NIMCET PYQ.
