A. 1/12
b. 1/24
c. 1/12
d. 1/4
I THINK these answers are correct, if this is for a major grade, ask somebody and compare my answers to theirs.

. P(at least one head) is the same as 1  P(no heads). Now, P(no heads) = 1/2 * 1/2 = 1/4 so P(at least one head) = 3/4. P(6) = 1/6. The total is 3/4 * 1/6 = 1/8.
actually for part a is it possible the answer could be 1/8?

Yes, the answer to (a) is 3/4 x 1/6 = 1/8
3/4 is the probability of getting at least one head in two coin tosses.
