Oops, how clumsy of me, I forgot to post the answers to those two Prof. Layton's puzzles I posted before going on holidays! So, without further ado, here they are:Q: There are 15 people stranded on a tourist boat which will sink in 20 minutes. Using the one lifeboat, which can carry a maximum of 5 people, move the people to the nearby island. The surrounding sea is full of man-eating sharks, so swimming is out of the question. If it the round trip from the ship to the island and back takes 9 minutes, how many passengers can be saved?
A:You can make 3 round trips in 20 minutes. But you can only save 4 people at a time as one person has to be the driver, therefore 12 people plus the driver survive, so the answer is 13.
Q: There are 10 jars each with 50 pieces of candy in them. These have been divided randomly into half, just by eyeball estimation, and then placed in separate bags. This made 20 bags. What is the probability that the average number of candies in one bag is 25?"
A: 100%. You have 10x50=500 pieces of candy and 20 bags. 500/20=25 pieces per bag on average.
