The probability that the first two votes drawn are both for candidate a is given by: 3C2/5C2 = 3/10 Having drawn two votes for candidate a on the first two draws, there are 2 votes for candidate b and one vote for candidate a remaining. The probability that a vote for candidate b will be drawn on the third draw is: 2/3. After the first three draws, there reains one vote for candidate a and one vote for candidate b. The probability that a vote for candidate a will be drawn on the fourth draw is: 1/2. The probability of the ordering aabab is therefore given by: The answer is: 0.1.
