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.). $$\begin{array} { c c }
\text { Simple Events } & \text { Probabilities } \
\text { SS } & 0.55 \
\text { SD } & 0.20 \
D S & 0.16 \
D D & 0.09
\end{array}$$ Find the probability that both patients survive.
A)0.36
B)0.3025
C)0.09
D)0.55
