    The animal colony in the reseach department contains 20 male rats and 30 female rats. Of the 20 males, 15 are white and 5 spotted. Of the 30 females, 15 are white, and 15 are spotted. Suppose that you randomly select 1 rate from this colony:

    a)Find the Joint probability table including the marginal probability.
    b) what is the probability of obtaining 1 female
    c)what is the probability of obtaining a white male
    d) which selection is more likely; a spotted male or a spotted female.
    e)Given that a rat is female, what is the probability that it is spotted.
