Which expressions are equivalent to -1/4 (16-12+8x)?

-1/4 (16-12+8x) =19

Step-by-step explanation:

1/10

Step-by-step explanation:

There are 6 marbles in the bag. 3 out of 6 are green.

3/6 = 1/2

So, he has a 1/2 of picking a green marble.

After getting a green marble, Joe doesn’t replace it meaning there are now only 5 marbles in the bag.

Since there’s one red marble in the bag the chance of trying one is 1/5.

Now to find the chance or drawing a green and red marble you need to do the equation:

1/2 x 1/5

This equals 1/10.

The probability is 1/10
