7/8 , 87,5% The easiest way is to turn the question around. No heads means that they are all tails and the priobability of all tails is 1/8 (everybtail 1/2 so 1/2 x 1/2 x 1/2) At least one head is therefore 1- 1/8 8/8-1/8 = 7/8 A more complicated way all 8 options are HHH,HHT,HTH, HTT, THH THT TTH TTT. (8 in total) seven do have atleast one head so 7/8. (Of course the same answer)
