Pretty standard question that has been asked before... keep flipping a coin until a winning combination appears (either HHT or HTT). Which strategy would you pick given the choice and why. Find the probabilities of winning associated with each strategy.

5 Answers

Essentially HHT is the better strategy. The probabilities are 2/3 HHT and 1/3 HTT. To see this if you draw a tree diagram (best to draw 4-5 iterations if you can't see it) and look at all the possible ways of winning. It turns out HHT is twice as likely to win hence the 2/3, 1/3 split.

By drawing 5 iterations, both HHT and HTT seem to make an appearance 7 times. How is HHT twice as likely to win?

The mathematical expectation of hte number of flipping for both compbinations is 25/2. In any case the probabilities of appearance of these compbinations are the same, so one can use both strategies with the same result. 50% 50%

1 Answer

You have a wall. It doesn't matter how big it is. You are given an Ivy (plant) which is set at the bottom of the wall. This Ivy grows at a rate which is squared the rate of the day before (ie. day 1: 1, day 2: 2, day 3: 4, day 4: 16, etc). If we buy another Ivy plant, putting it on the opposite side of the wall, which performs in the same way to the first, how much time would we be gaining?
