WebbIf you see the sample space, the probability of any combination of tails and heads for ten times is 1/512. (ie) P (HHHHHHHHHH) as well as P (HHHHHHHHHT) or even P (HTHTHHTTHT) is the same 1/512. Hope this answers your question. 4 comments ( 9 votes) Forrest T 6 years ago WebbWhen 3 coins are tossed, the possible outcomes can be {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}. Thus, total number of possible outcomes = 8. Getting at least 2 tails includes {HTT, THT, TTH, TTT} outcomes. So number of desired outcomes = 4. Therefore, probability of getting at least 2 tails =. WebbAs an example, to calculate the probability of achieving 12 to 20 heads out of 20 coin flips, you would enter "=1-BINOMDIST(11,20,0.5,true)". This effectively calculates the chance of achieving no more than 11 heads out of 20 coin flips, but then subtracts it from one, which results in the probability of 12 to 20 heads out of 20 flips. drawback\u0027s 7u
