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
$19.50
We can turn these into equations by making the shirts 's' and the ties 't'.
4s+2t=95 and 3s+3t=84
Now we can solve the system of equations with substitution.
