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.

Answer:
⇒ [Factorized form]
Step-by-step explanation:
Given expression:
We need to make the subject.
In order to do that we need to solve the expression for in terms of
and
We have,
Subtracting both sides by
Taking square root both sides in order to remove square of
The difference of squares can be factorized and written as:
[difference of squares
