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
lbvjy [14]

Answer:

4.51\times10^{-10}

Step-by-step explanation:

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

\frac{64 * 63 * 62 * 61 * 60 * 59 * 58 * 57}{8!} = \frac{1.78\times10^{14}}{40320} = 4426165368 possible combination

So the probability is pretty thin

P = 2 / 4426165368 = 4.51\times10^{-10}

3 fraction equivalent to 4/7
GalinKa [24]

Answer: 8/14, 12/21, and 288/504

Step-by-step explanation: To find 3 fractions that are equivalent to 4/7, we either multiply or divide the numerator and denominator by the same number.

If we multiply 4/7 by 2 in both the numerator and denominator, we get the equivalent fraction 8/14.

If we multiply 4/7 by 3 in both the numerator and denominator, we get the equivalent fraction 12/21.

If we multiply 4/7 by 72 in both the numerator and denominator, we get the equivalent fraction 288/504.

These are just 3 possible answers.

Let P be a point not on the line L that passes through the points Q and R. The distance d from the point P to the line L is d =
Goshia [24]

Answer:

Distance from point (0,1,1) to the given line is zero.

Step-by-step explanation:

Given parametric equations of line,

x=2t, y=5-2t, z=1+t

To find distance from (0,1,1), we have to eliminate t from above equations so that,

y=5-2t=5-x\implies x+y=5=4+1=4+z-t=4+z-\frac{1}{2}x

\implies 3x+2y-2z-8=0\hfill (1)

whose direction ratioes are (l,m,n)=(3,2,-2) and distance fro point (a,b,c)=(0,1,1) is given by,

\frac{al+bm+cn}{\sqrt{l62+m^2+n^2}}=\frac{(3\times 0)+(2\times 1)+(-2)(1)}{\sqrt{3^2+2^2+(-2)^2}}=\frac{0+2-2}{\sqrt{17}}=0

Distance between point (0,1,1) and (1) is zero. That is point 90,1,1) is lies on the line (1).
