Answer:

63 in 64 chance

Explanation:

If you for one coin it would be a 50% chance so you multiply that
(1)/(2)^(6) which would be the probability of no heads 1/64 and at least 1 head you would
1-(1)/(64) which is
(63)/(64). Ask me if you have any further questions

63 in 64 chance


With 6 coins you times by 2 and minus by 1 again resulting in a 63 in 64 chance. To find the chance of getting at least one heads if you flip ten coins you times 64 by 2 four times or by 16 once and then minus 1, this results in a 1063 in 1064 chance of getting at least one heads.
