Essay

A hospital reports that two patients have been admitted who have contracted Crohn's disease. Suppose our experiment consists of observing whether each patient survives or dies as a result of the disease. The simple events and probabilities of their occurrences are shown in the table (where S in the first position means that patient 1 survives, D in the first position means that patient 1 dies, etc.).
$$\begin{array} { c c } \text { Simple Events } & \text { Probabilities } \\\text { SS } & 0.58 \\S D & 0.12 \\D S & 0.10 \\D D & 0.20\end{array}$$ Find the probability that neither patient survives.
