Can youanswer this question pls.

The random variable Xcan take one of the three discrete values: 1. 2 or 4. The probabiiity mass function '5 such that P(X = 1) = (I. P(.X = 2) = kc: and P(.X = 4) = 3a, where a and k are positive constants. Compute P[X > 2] given that E[X) : 17/6. Give your answer to 3 declmai pieces
