Mike recorded whether it rained each weekday and weekend day for 10 weeks. His results are summarized in the table below.

$$\text{Weekday and Weekend Day Rain for 10 Weeks}$$ $$\begin{array} {|l|c|c|c|} \hline & \text{Rain} & \text{No rain} & \text{Total} \\ \hline \text{Number of weekdays} & 9 & 41 & 50 \\ \hline \text{Number of weekend days} & 5 & 15 & 20 \\ \hline \text{Total} & 14 & 56 & 70 \\ \hline \end{array}$$

If one of the days on which there was rain is selected at random, what is the probability the day was a weekend?

We need to find the following from the table:

$$\frac{\text{weekend}}{\text{days with rain}}$$ $$\text{Weekday and Weekend Day Rain for 10 Weeks}$$ $$\begin{array} {|l|c|c|c|} \hline & \text{Rain} & \text{No rain} & \text{Total} \\ \hline \text{Number of weekdays} & 9 & 41 & 50 \\ \hline \text{Number of weekend days} & \colorbox{yellow}{$5$} & 15 & 20 \\ \hline \text{Total} & \colorbox{aqua}{$14$} & 56 & 70 \\ \hline \end{array}$$

Out of the 14 days where there was rain, 5 was on a weekend.
