Simple (probability?) question.

I can't figure out this simple seeming question:

Suppose people can have one of two preferences: A or B (Coke or Pepsi
if you prefer). On average 50% of people prefer A, but 60% of redheads
prefer A and 75% of catholics prefer A. What percentage of redheaded
catholics prefer A?

Any thoughts?
