At the Kenya medical research institute a new drug is being tried. A sample of eighty sick rats is being used. Sixty of these rats are given drugs and the rest are not. A half of those given drugs are put on a high calorie diet while three quarters of those who are not given drugs were put on the same diet. For the ones who are treated and put on a high calorie diet the probability of dying is 0.1 and 0.2 if not put on a high calorie diet. For the ones who are not treated and put on a high calorie diet the probability of dying is 0.4 and 0.6 if not put on a high calorie diet.
a.Draw a tree diagram to represent the above information.
b.Calculate the probability that a rat picked at random
i.Is given drugs, put on a high calorie diet and will die
ii.Is given drugs and will die .
iii.Will die
iv.Is not given drugs and will not die
