a)
Probability is
1=4 so B is the correct answer for this problem.
The order Queen Zubaida picks a Satrap and a Vizier does not matter. Since order does not matter, combination is used.
Using a calculator, we solve for nCr = 12C2 = 66 ways..
Or using the combination formula C(n,r) = n!/[(n-r)!r!]
C(12, 2) = 12!/[(10!)(2!)] = 66 ways.
X axis is 3 and y axis is -8
By solving this problem, I got D.-8.Right?
