Probability question

The table shows, for some particular year, a listing of several income levels and, for each level, the proportion of the population in the level and the probability that a person in that level bought a new car during the year. Given that one of the people who bought a new car during that year is randomly selected, find the probability that the person was in the $35,000 - $39,999 income category. Round your answer to the nearest hundredth.
