Probability Calculator

Change Sequence:

The probability of flipping this sequence is 1 in 1024

Using the Probability Calculator

To use this Probability Calculator just enter your required sequence structure into the Change Sequence text box above. The sequence structure should use the letters 'h' and 't' to represent 'heads' and 'tails' respectively - you can use either upper or lowercase letters or a mixture of both if that's your thing. For example, if you want to use the sequence (tail, heads, tails, tails, heads, tails, heads, heads) then change the sequence structure in the text box to (thtththh).

Unlike the probability calculator on our coin flipper Flipping 10 heads in a row this calculator is not limited to a length of 20 coins.
