PROBLEM 12E

You are a member of a class of 18 students. A bowl contains 18 chips: 1 blue and 17 red. Each student is to take 1 chip from the bowl without replacement. The student who draws the blue chip is guaranteed an A for the course.

(a) If you have a choice of drawing first, fifth, or last, which position would you choose? Justify your choice on the basis of probability.

(b) Suppose the bowl contains 2 blue and 16 red chips. What position would you now choose?

Step-by-Step Solution:

Step 1 of 4

a) No. of chips=18

Blue chips=1

Red chips=17

P(1st person draw blue chip)=1/18

P(2nd  person draw blue chip)

=P(1st person did not draw blue chip)*P(2nd person draw blue chip)

=17/18*1/17=1/18

P(3rd person draw blue chip)

=P(1st & 2nd  person did not draw blue chip) * P(3rd person draw blue chip)

=17/18*16/17*1/16=1/18

Step 2 of 4
