There are only 2 solutions for none of the rooks can capture any of the other rooks: only if they are laid out in either of the 2 diagonal of the chess board
The number of possible combination for the rock to laid out in 8x8 (64 slots) chess board
possible combination
So the probability is pretty thin

Answer:
Option B: (½•16)⅓
Step-by-step explanation:
The associative property states that we can add or multiply numbers in a group regardless of how those numbers are grouped. And that we will get the same answer.
For example;
x(y•z) = (x•y)z = (x•z)y
Now in our question, we want o evaluate; ½(16•⅓)
Using the associative property, the best expression will be: (½•16)⅓
It's the best expression because the terms in the bracket are easy to multiply out without remainder.
Thus, option B is correct
Answer:
359.94 = 59.99 * X
Step-by-step explanation:
The situation is determined by the following equation:
T = M * X
Being M the monthly value, that is to say 59.99
T the total value, that is 359.94
And X would be the number of months, and at the same time the variable.
In this case it would be like this:
359.94 = 59.99 * X
If we solve for X, we are left with:
X = 359.94 / 59.99
X = 6
