Color blindness is an inherited characteristic that is more common in males than females. Let F represent female, and C represent red-green color blindness. P(C) = 0.039 P(F and C) = 0.004 P(F or C) = 0.548

2. Use the Addition Rule or the "OR" formula for probability, substitute the values given, and solve for the probability of a Female.

P(F or C) = P(F) + P(C) - P(F and C)
