Answer:
1−126=1−164=6364 .
Explanation:
If you think of the tosses as a sequence of 6 flips, there are 26 total possibilities.
There is only 1 way to get all heads, so the probability of getting all heads is 126=164 .
To get the probability of getting at least one head, this is the opposite of the probability of getting no heads - i.e. all tails.
The probability of getting all tails is 126=164 .
To get the probability of getting at least one head, we subtract this from 1 to get:
1−126=1−164=6364 .
