Let R be the space of all the N! permutations of (1,2,...N), and let R = (R1, ...Rn) be uniformly distributed over R. Prove that (i) P(Ri=k) = 1/N; 1<=i, k<=N. (ii)P(Ri=k, Rj=h) = 1/N(N-1), 1<= i ≠j, k≠h<=N (iii)P(Ri=k, Rj=k) = 0, 1<=i≠j, k<=N.

step-by-step explanation:

step 1: simplify both sides of the equation.

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
