Let \(X\) denote the number of hours you play during a randomly selected day. The probability that \(X\) can take values \(x\) has the following form, where \(c\) is some constant.
\(P(X = x) = 0.1\) if \(x = 0\); \(cx\) if \(x = 1\) or \(x = 2\); \(c(5 - x)\) if \(x = 3\) or \(x = 4\); 0 otherwise.
Match List-I with List-II :
List-I | List-II
(A) c | (I) 0.75
(B) P(X \(\le\) 2) | (II) 0.3
(C) P(X = 2) | (III) 0.55
(D) P(X \(\ge\) 2) | (IV) 0.15
