A random variable \( \mathrm{X} \) has the following probability distribution :
\( \begin{array}{rllllll}\mathrm{X} & : & 1 & 2 & 3 & 4 & 5 \\ \mathrm{P}(\mathrm{X}): & \mathrm{K}^{2} & 2 \mathrm{~K} & \mathrm{~K} & 2 \mathrm{~K} & 5 \mathrm{~K}^{2}\end{array} \)
\( \mathrm{P} \) Then \( P(X2) \) is equal to :
W
(1) \( \frac{7}{12} \)
(2) \( \frac{23}{36} \)
(3) \( \frac{1}{36} \)
(4) \( \frac{1}{6} \)
