    An easy way to think about it is to take the table above and assume each percentage point corresponds to one person - so, 100 people total. Then,

    a) There are 44 people with blood type O - 38 of them are Rh+, and 6 are Rh-. Then the odds of being Rh- with type O blood are 6/44.

    b) Similarly - 85 people are Rh+. 9 of them have blood type B, so 9/85 is the probability.
