Eights rooks are placed randomly on a chess board. What is the probability that none of the rooks can capture any of the other r

erastova [34]

Answer:

The probability is $\frac{56!}{64!}$

Step-by-step explanation:

We can divide the amount of favourable cases by the total amount of cases.

The total amount of cases is the total amount of ways to put 8 rooks on a chessboard. Since a chessboard has 64 squares, this number is the combinatorial number of 64 with 8, $64 \choose 8 .$

For a favourable case, you need one rook on each column, and for each column the correspondent rook should be in a diferent row than the rest of the rooks. A favourable case can be represented by a bijective function $f : A \rightarrow A ,$ with A = {1,2,3,4,5,6,7,8}. f(i) = j represents that the rook located in the column i is located in the row j.

Thus, the total of favourable cases is equal to the total amount of bijective functions between a set of 8 elements. This amount is 8!, because we have 8 possibilities for the first column, 7 for the second one, 6 on the third one, and so on.

We can conclude that the probability for 8 rooks not being able to capture themselves is

$\frac{8!}{64 \choose 8} = \frac{8!}{\frac{64!}{8!56!}} = \frac{56!}{64!}$

ruslelena [56]

$-\dfrac{1}{3}b=9\ \ \ |multiply\ both\ sides\ by\ (-3)\\\\-3\cdot\left(-\dfrac{1}{3}b\right)=-3\cdot9\\\\\huge\boxed{b=-27}\leftarrow\boxed{C}$

Answer:

Hope this helps :)

Step-by-step explanation:

(3^5)÷(3^5)

Simplify 3^5

243÷243

(3^5)÷(3^5)

3^5/3^5=3^5-5

3^5-5

3^5-5= 1

Formula: x^a/x^b=x^a-b

2^10/2^10

Cancel out 2^10

2^10/2^10

2^10/2^10=2^10-10

2^10-10

2^10-10=1

Formula: x^a/x^b=x^a-b

x^7/x^7x≠0

x≠0

(4x+2y)5÷(4x+2y)^5(4x+2y) ≠ 0

5/(4x+2y)^3 ≠ 0
