I need a bit of help, I am good at probability but the wording of this problem has confused me a bit?

Question

It says: You flip a coin three times. What is the probability that at least one of the outcomes will be tails?

It says AT LEAST ONCE.

anonymous · Answer

well since you will flip it 3 times so the probabillity is 1/3 i guess

anonymous · Answer

I mean, it makes sense logically but she says I need to show steps. The thing I was thinking, of all the times I flip it, it would be 1/2 so what's next?

anonymous · Answer

no its 1/3 since ull flip it 3 time...
if ud flip it 2 then its 1/2
