In a survey conducted by Health Ministry on prevalence of diabetes disease among senior citizens, those above 60 year-old, the following are the published information: 55% of the respondents are Malay and 25% of them are diabetics; 25% of the respondents are Chinese and 20% of them are diabetics; 20% of the respondents are Indian and 15% of them are diabetics. a) Illustrate the above published information in a tree diagram. If a senior citizen is picked at random, find the probability that he/she is a diabetic. (b) (c) Suppose that a senior citizen is diabetic, find the probability that he/she is Malay.

A student can study 0 or 1 hour for a statistics test on any given night. Draw a tree diagram to find out the number of ways in which the student can study a total of exactly two hours on three consecutive nights.
A financial planner has three portfolios: A, B, and C. Because investors have different tolerances for risks, 20% of people are likely to invest in portfolio A, 30% more likely to invest in B, and 50% more likely to invest in C. Each portfolio has both stocks and bonds, and investors are equally likely to choose either. This is a tree diagram that represents the probability of investors choosing the different financial products. What is the value of Z?
