think of what the question is really asking. "at least one of or "
and what does A + B + C + D mean.
good luck,
I am doing the following question.
"5. How many poker hands are there that contain at least one of 10@, QB, AC, or 6D ?
Show your work."
For my solution I did
A=52*(51C4)
B=52*51*(50C3)
C=52*51*50*(49C2)
D=52*51*50*49*(48C1)
then
A+B+C+D=E
Does this seem to make sense?
The question asks at least 1.
So that means how many ways are can you get one of them or two of them or three or all 4 of them.
A=the amount of ways to get 1
B=the amount of ways to get 2
C=the amount of ways to get 3
D=the amount of ways to get 4
edit: I did mess up though. It should be
A=52*(51C4)
B=(13C2)(4)(4)(50C3)
C=(13C3)(4)(4)(4)(49C2)
D=(13C4)(4)(4)(4)(4)(48C1)
