yep, i put 50% AKA B.ok so for the one where tails has been tossed 9 times, what it the probablity of it being thrown a tenth toss, did you all put B (1/2). Because i think thats the answer. Its different than them saying what is the probability of throwing tails 10 times in a row. (which is 1/2^10). Because that throw itself solely has a probablility of 1/2. Do you all agree?
