Probability of card draw in a TCG

[Guest]

Hello and many thanks to whom ever can help me with this tricky question my friends and i have been having. So here is the problem.

In a deck of 60 cards there are 4 identical cards. What is the probability to draw one of those cards if you draw an opening hand of 7 cards.

answer = 1 - probability of not drawing any of those 4 = [tex]\boxed{1-\frac{^{56}C_7}{^{60}C_7}}[/tex]
