Step-by-step explanation:
As stated in the question, the probability to toss a coin and turn up heads in the first try is , in the second is
, in the third is
and so on. Then, P(C) is given by the next sum:
This is a geometric series with factor . Then is convergent to
. With this we have proved that P(C)=1.
Now, observe that
Then
