Total possible outcomes are 2^10 = 1024.

Now in half the cases the 3rd coin will have a head and the other half will have tails.

So 512 (2^9) cases head and 512(2^9) cases tail. E IMO

each coin can have two outcomes either head or tell... so if u particular any outcomes. in the case , 3rd as head or tell. other 9 outcomes can be both head or tell. so total of 512 outcomes are there in which third outcome is head or tail
