good evening, if not too much stress could you explain how you solved for each bullet point

A continuous RV, x has probability distribution function (PDF) as defined below: p(x) = k1 for asxsb = K2 for buxsc where k1 and k2 are positive constants; further, (a = 2, b = 3, c = 4), Px[a s x s b] = 0.550 and Px [b s X S c] = 0.450 Determine the following: . Values of k1 and k2 . Expected value of the RV . Variance of the RV distribution . Median value of the RV . CDF values: Px[a to (x
