Answer: 1 in 8, or 12.5% chance.

Step-by-step explanation: If there is a 50-50 chance in landing heads on the first flip, and you land it, there was a 50%chance. To flip it again would be another 50-50 chance. Half of 50% is 25%, or 1 in 4. To land it again would be half of 25%, which is 12.5%, or 1 in 8 chance.
