First off Mel is a she :/

Also I might be wrong but:
The p(face up) is (50/100) aka 1/3.
The p(face down) is 100/150) aka 2/3.
Then it asks for an estimate of it landing face up then face down so we need to multiply the probabilities.
So 1/3*2/3 which is 2/9. I feel I am wrong though because is asks for an estimate. Anyone else?
