.55*X=231 .....X=231/.55.......X= 420
Your answer would be (3,0)
The median for the problem is 56.5
Answer:
If the positions are distinct, as in executive offices, then P(9,5)
P(9,5) = 9!/(9 - 5)! = 15120..... is the answer
But...
If the positions are equivalent, such as seats in a legislative body, then C(9,5)
C(9,5) = 9!/[(9 - 5)!(5!)] = 126
Hope this can help you :)
