Answer:
28/289
Step-by-step explanation:
7 red, 4 blue, and 6 white = 17 marbles
P ( red ) = number of red / total
= 7/17
Replace the marble
7 red, 4 blue, and 6 white = 17 marbles
P ( blue ) = number of blue / total
= 4/17
P (red, replace, blue) = 7/17* 4/17
=28/289
Answer:

Step-by-step explanation:
To write the factored form, multiply a*c from the standard form
. Here it is 4*1 = 4.
Then find factors of 4 that add to b=-4.
4: 1,2,4
-2+-2 = -4
Split the middle term into -2x+-2x and factor by grouping.
