You guys said getting a head meaning one head...
Using a sample space,
You get HH HT TH TT
The possibilities with a head are 2/4... making it 1/2
Innit? I feel like myschool should've put their own explanation...

Gutting - not getting head
Two fair coins
1/2 × 1/2
= 1/4
1- (pr two fair coins)
1-1/4
3/4

Since 2 fair coins are tossed it means it has 4 faces in total which contains 2 head and 2 tails and probability of getting heads is 2/4=1/2
So therefore, the probability of getting heads is 1/2
