Let x be a discrete random variable with the probability function f(x) = kx^3 + 0.15 for x = -1,0,1,2 find the value of k
Find the following quantities also: f(0)=, F(0)=, f(1.5)=, F(1.5)=, P(0
Also find the mean μ (exact), the variance σ², and the standard deviation σ ( both rounded to three decimal places) of this random variable.
