A hospital reports that two patients have been admitted who have contracted Crohnʹs
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.). $$\begin{array} { c c }
\text { Simple Events } & \text { Probabilities } \
S S & 0.53 \
S D & 0.12 \
D S & 0.17 \
D D & 0.18
\end{array}$$ Find the probability that neither patient survives.
