Are these sentences natural to a native ear? 2016 Dec 9

Hi,

Are these sentences natural to a native ear?

[color=blue]1. I was looking for this kind of hat to give it to a friend. (Is the ‘it’ necessary?)

  1. My leg just fell asleep. ( I said this to explain why I was not able to walk after getting off from a chair).

  2. A good test to check if someone is bad at math is to ask them what’s their strategy when they play roulette. (I don’t necessarily agree with this view).

Thanks.

  1. If you are after a natural sentence, leave out ‘it’.
  2. Informally, fine.
  3. … to ask them what is their strategy… - is also possible.

Thanks Beeesneees.
