The result of rolling a fair die 150 times is as summarized in the table given.\(\begin{array}{c|cccccc} \text{Number} &amp; 1 &amp; 2 &amp; 3 &amp; 4 &amp; 5 &amp; 6 \\ \hline \text{Frequency} &amp; 12 &amp; 18 &amp; x &amp; 30 &amp; 2x &amp; 45\end{array}\)What is the probability of obtaining a 5?
