- Aug 17, 2012 · I took this as a challenge and developed recurrence relations that give you the probability of heads or tails for a biased coin. The answer to your question is 92.617% for 3 red or 3 green, so 7.383% for neither. You can use the old recurrence for 3 reds and for 3 greens separately as that also works for a biased coin.
- Suppose I have an unfair coin, and the probability of flip a head (H) is p, probability of flip a tail (T) is (1-p). If I flip the coin 6 times, wondering if the probability of HTT???, and the probability of THT???, and the probability of TTH??? are the same? Suppose each flip is independent. ? means do not care if head or tail. Thanks.
