$300 - Misconceptions In a certain town there are two hospitals, a small one in which there are, on the average, about 15 births a day and a big one in which there are, on the average, about 45 births a day. The likelihood of giving birth to a boy is about 50%. In the small hospital a record has been kept during the year of the days in which the total number of boys born was greater than 9, which represents more than 60% of the total births in the small hospital. In the big hospital, they have kept a record during the year of the days in which there were more than 27 boys born, which represents more than 60% of the births.

$500 Question from H5 Jim and Bill each receive a box containing two white marbles and two black marbles. A. Jim extracts a marble from his box and finds out that it is a white one. Without replacing the first marble, he extracts a second marble. Is the likelihood that this second marble is also white (smaller than, equal to, or greater than) the likelihood that it is a black marble? B. Bill extracts a marble from his box and puts it aside without looking at it. He then extracts a second marble and sees that it is white. Is the likelihood that the first marble he extracted is white (smaller than, equal to, or greater than) the likelihood that it is black?

$500 Answer from H5 A.Smaller since P(W|W) = 1/3 and P(B|W) = 2/3 B. Smaller since first draw had to be out of one white and two black, probability of white was smaller.
