This question is as wrong as it's politically loaded. The probability for the climate scientist to have two properties can't be higher than the probability for the climate scientist to have one of those two properties. –  joriki Feb 12 '13 at 1:48
    
So tempted to replace the political language with generic phrases like "The probability that an object has property $A$ is $.1$" –  Daniel Rust Jul 4 at 0:22

1 Answer 1

Hint: draw a Venn diagram and label each region with the fraction of the universe it contains. It has four regions, you have three constants plus the fact that all the regions sum to $1$.
