Explanation of Solution
Given:
The given condition is 90% survive the kidney transplant but 10% die.
The transplant succeeds in 60% of those who survive, and other 40% must return to kidney dialysis.
The proportion who survive five years are 70% for those with a new kidney and 50% for those who return to dialysis.
Calculation:
There are two options, thus two branches are nedded at each knot:
The probability is the number of favourable outcomesdivided by the number of possible outcomes:
b.
To find: the probability that Morris will survive for 5 years.
