These paradoxes are great examples of the value and power of mathematics to identify and explain the truth when there are gaps in our natural intuition. Note that this answer works for any odd number of coin flips. Solution 2. a total run of 8), a 25 chance that the next two steps are another run of 7 each and so on. 5, then realize that rand () is uniform random number generator between 0,1, so you can assign the output of rand () accordingly.

The above explanation will help us to solve the problems of finding the probability of tossing three coins. When we flip the coin 9 times there are 2 9 possible outcomes that can happen.

The probability that the coin lands on heads 2 times or fewer is 0. Use a martingale argument to compute the expected number of flips until the following sequences appear (a) HHTTHHT (b) HTHTHTH Question 6. Practice this lesson yourself on KhanAcademy. The probability a sequence of N flips is all heads is 2 -N. Therefore, N could be any non-negative integer. By applying Bayes theorem, uses the result to update the prior probabilities (the 101-dimensional array created in Step 1) of all possible bias values. Therefore, the probability is 10 5 210 63 256 (b) There are more heads than tails.
