I was waiting for my kids one day and started watching the cars go past; I thought there seemed to be a lot of white Holdens so started to record the make and color of cars that went past. This table shows the results.

Use the table to answer the following:
a) The probability that a randomly chosen car is white.
b) The probability that a randomly chosen car is silver or white.
c) The probability that a randomly chosen car is a white Holden.
d) The probability that a randomly chosen car is white or a Holden.
e) The probability that a randomly chosen car is a Toyota.
f) The probability that a randomly chosen Ford is white.
g) The probability that a randomly chosen white car is a Holden.
h) The probability that a randomly chosen Holden car is white.
i) Give an example of disjoint events from the above table.
j) Give an example of exhaustive events from the above table.
k) Are the events: “white” and “Holden” independent?
l) This table is based on data I observed at 1 location and 1 time. BRIEFLY note down 2 ways in which bias could have entered these data.
m) Suggest a better way of finding out the colors of cars. (Briefly!)
