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.
The work and answer is shown in the image below. Just set the variables and solve.
1cm is equal to 10mm, so 37cm is the same as 370mm
1cm is equal to 0.01m, so 37cm is the same as 0.37m
Answer:
B. A value of x = 27 results in congruent triangle.
