Answer:
4/663
Step-by-step explanation:
There are four queens. The probability that the first card is a queen is 4/52.
There are four kings. There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.
Therefore, the probability that the first card is a queen AND the second card is a king is:
P = 4/52 × 4/51
P = 4/663
I'm guessing you want an equation.
In that case, the equation would be $2x =y
Answer:

Step-by-step explanation:
We have the following equations:


If we want to add these equations, we just need to add x-terms, y-terms and independent terms.


I hope it helps you!
