Head and tails is a game that only gives a 50/50 chance so if it lands on tails it could land on head and repeat but it always very so nothing is so sure my answer is 50/50 chance

Answer:

12.5%

Step-by-step explanation:

The answer to this is 12.5% and you can calculate by multiplying the possibility of getting heads or tails, which would be 1/2, and then multiply it by the next one:

(1/2)(1/2)(1/2)=1/8

1/8=.125

The answer in percentage for the probability that heads only appears on the last one would be 12.5%
