Q: You have one litre of household bleach, a six-litre bottle of Pam's natural spring water, an empty 300ml Speights can and a 20-litre bucket. Assuming that you weigh 91kg and have drunk a further nine (9) cans of Speights Gold:

a) How long will it take you to work out how to make 15 litres of a 2% bleach solution?

b) How much of the final 15 litres will you spill on your trousers?

c) What is the probability that you will at some point drink the bleach solution instead of the spring water?
