There are 10 total marbles and three are pink. So you are to determine the probability of choosing a pink marble, placing it back in the bag and choosing another pink marble.
The probability of choosing a pink marble is # of pink marbles to # of all marbles which is 3/10. Since we place the marble back in the bag, the probability is the same for the second time.
To determine the probability of both occurrences, we need to multiply 3/10 x 3/10 which is 9/100. This can be written as 9:100 as a ratio.

Your attachment says: (-1/2) · (4x) · (-2) · (7y) · (-1)

Let's put together the
1st, 3rd, and 5th factors: (-1/2) · (-2) · (-1) = -1

So now we have    (-1) · (4x) · (7y)

Well       (4x) · (7y) = (4 · 7) · (x · y) = 28 · x · y

So all together we have    (-1) · (28 · x · y) = -28xy

$\left(-(1)/(2)\right)(4x)(-2)(7y)(-1)\n\n=\left(-(1)/(2)\right)(-2)(4)(7)(-1)(x)(y)\n\n=(1)(4)(7)(-1)(xy)\n\n=(28)(-1)(xy)\n\n=(-28)(xy)\n\n=\boxed{-28xy}\to\boxed{\boxed{A}}$
