Hello,
The key to doing these problems is writing the fraction for each event and multiplying them.
I will do the first problem for you.
First, you have to draw an ace. The chances of that are 4/52.
Then, you have to draw a jack. The chances of that are 4/51.
We changed 52 to 51, because we didn't replace the ace that we drew the first time.
Multiplying those fractions gives us the answer 4/663.
I hope this gets you started in the right directions,

Step-by-step explanation:
when x = -1
y= 3x - 1
3(-1) - 1
-3 -1
-4
when x = 0
y = 3x - 1
3(0) - 1
0 - 1
-1
when x = 2
y = 3x -1
3(2) - 1
6 - 1
5
I think you divide 1/2 by -2/5 and then add that to -1/4....
