    Focus on the "state B" column only. What is the value in the bottom of this column?

    now you divide those two values 15/35 = 3/7

    so the probability of picking a conservative person, given they're from state B, is 3/7

    Thanks! It wants it in decimal form and rounded, which would be .43
