#### Answer:

1/7

#### Explanation:

There are only 7 possible combinations:

(let T=tail, H=head)

TTTT

HHHH

THHH

TTHH

TTTH

HTTT

HHHT

The result's are like that since when you do it actually, that's the only possible combinations. You won't mind the order, only the number of appearance of either head or tail.
