    Odds for male = 1.538

    Odds for female = 0.65

    Step-by-step explanation:

    The question is asking for odds, not a probability. A probability shows how much the chance for the event to happen, so it can be expressed as a percentage. Odds show how the event more likely to happen compared to the chance it did not happen. If an event has a 90% probability, the odds will be 90:10 = 9

    In this case, the odds of selecting a male will be:

    number of male : number of female = 20:13 = 1.538

    The odds of selecting a female will be

    number of female : number of male = 13/20 = 0.65
