c) A division fact of a÷b=c is equivalent to the division fact a÷c=b.

Therefore 8.58÷=3.9 is equivalent to the division fact 8.58÷3.9=.

Since 8.58÷3.9=2.2, then 8.58÷2.2=3.9.
d) A multiplication fact of a×b=ca×b=c is equivalent to the division fact b=c÷a.

Therefore 3.2×=24 is equivalent to the division fact =24÷(3.2).

Since 24÷(3.2)=7.524÷(3.2)=7.5, then 3.2×7.5=24.

I have a random variable ξ with function distribution (f.d.) G . Define the p −dimensional random vector as
X = ( ψ 1 ξ , . . . , ψ p ξ ) F ( F  is f.d. )

Given a > 0, consider A = [ a , a ] p . I want to find an expression for:
A d F
involving G and the ψ s
My attempt is first try to find the f.d. of X:
F ( x 1 , . . . , x p ) = P [ ψ 1 ξ x 1 , . . . , ψ p ξ x p ] = P [ ξ x 1 ψ 1 , . . . , ξ x p ψ p ] = P [ ξ n min { x 1 ψ 1 , . . . , x p ψ p } ] = G ( min { x 1 ψ 1 , . . . , x p ψ p } )
Even with these expressions in hand, I'm having serious trouble finding an expression for A d F.
