Answer: 1/2
Is this correct?
Could you please explain if I got it wrong?
Thanks.

No. Figure the probability of getting three tails in three tosses, then the probability of getting at least one head is that subtracted from one.
Pr(atleastoneHead)=1Pr(three tails)

notice that there are 7 with at least one H, and only one with no H
so the odds in favour of getting at least one head in three successive flips of a coin is 7:1
(I hope you meant "odds" and not probability.
The prob of at least one head is 7/8
odds in favour of some some event = (prob of that event):(prob of NOT that event)
