Look at the picture part 1
Lesechka [4]

We are given equation y = -3x^2.

We need to check the given table.

We have x=-2,-1,0,1,2 in the given table.

Plugging x=-2,-1,0,1,2 in the given equation

For x=-2

y = -3 (-2)^2 = -3(4) = -12

For x =-1

y = -3 (-1)^2 = -3(1) = -3

For x =-0

y = -3 (0)^2 = -3(0) = 0

For x =1

y = -3 (1)^2 = -3(1) = -3

For x =2

y = -3 (2)^2 = -3(4) = -12.

Therefore, correct table is

<h3>   x       y      (x,y)</h3><h3>_____________</h3><h3>  -2   -12       (-2,-12)</h3><h3>  -1    -3        (-1,-3)</h3><h3>   0    0        (0,0)</h3><h3>   1     -3        (1,-3)</h3><h3>   2    -12       (2,-12).</h3><h3>________________</h3>

In order to find the chance of both, you'll need to multiply the fractions together, giving you the 1/380 chance.

ANSWER:
Option 4 - 1/380


Hope this helps!! :)
