Number defective=4
number of non-defective=total-defective
=20-4
=16
the questions asked for 1 defective
so we choose only 1 defective from 4 defective items
4C1
and for 1 non-defective
we choose only 1 non-defective from 16 non-defective items
16C1
we choose 2 items from 20 items
so 20C2
answer:
probability= [(4C1) * (16C1)] /(20C2)
=32/95

To graph the line 
we are going to take advantage of the fact that its y-intercept is -2 when x=0, so our first point is (0,-2). To find our second point, we are going to find the x-intercept; to do it, we are going to set y=0 and solve for x:
Now that we have our second point
, we just need to join our two points with a straight line.
We can conclude that the graph of <span>y=-3/4X-2 is:</span>
Now that we have our second point
We can conclude that the graph of <span>y=-3/4X-2 is:</span>
