Hi Tony
good to have you back on board fella.
As ADB says, it is a half chance multiplied by a half chance for either scenario. Which is, a quarter chance. And then 1/4 chance + 1/4 chance for the 2 consecutive heads OR tails option, if you are not fussy about whether you want a head or tail.
If you spend long enough at it, you will eventually get 10 heads or tails in a row, like that Derren Brown fella. But it took him about 14 hours of filming before he actually achieved this. |
