Question 3

Suppose that for a particular piece of machinery, the frequency distribution of monthly breakdowns is as follows:   Number of Breakdowns  Prob. 00.5010.2520.1030.1040.05\begin{array} { c c } \hline 	ext { Number of Breakdowns } & 	ext { Prob. } \0 & 0.50 \1 & 0.25 \2 & 0.10 \3 & 0.10 \4 & 0.05\end{array} Number of Breakdowns 01234​ Prob. 0.500.250.100.100.05​​
