We know that $P(D\cap E)=P(D)P(E)=\boxed{0.1134}$ .

And $P(D\cup E)=P(D)+P(E)-P(D\cap E)=\boxed{0.5766}$ .

Hope this helps.

X+y=-1
3x-y=21
add them equations

x+y=-1
3x-y=21 +
4x+0y=20

4x=20
divide by 4
x=5

x+y=-1
5+y=-1
minus 5 both sides
y=-6

I would say parallelogram. So the rectangle still fits but more shapes can be applied.

Your answer is A

It cannot be C because the line y > -2 uses the (>) greater than symbol.

When equations have a greater than symbol, they are graphed using a dotted line.

It cannot be D because the line is y ≤ - l x-1 l

with the less than or equal to sign (≤) , you use a solid line to graph

With the greater than symbol for y > -2 , the shaded region must be above this line.

With the less than or equal to sign in y ≤ - l x-1 l , the shaded region must be below the line.

Hope I helped - message me if you have any questions :)
