I don't know this stackexchange's policy on homework, so I'll give hints. What are the possible sequences leading up to TT or TH, but not including either one? Are these sequences different? – TimWescott Sep 27 '22 at 20:33
See https://stats.stackexchange.com/questions/12174/ and https://stats.stackexchange.com/questions/544811 for some methods. – whuber Sep 27 '22 at 21:55
