courtney,
i'm sorry, i don't understand this response. does it mean the first answer 3/11 is incorrect?

probability 
bobpursley,
Pr(both)=Pr(both black) + prob(white)
= 4/11*3/10 + 7/11*6/10

Mr. Pursley,
thank you for taking the time to answer my question. i very much appreciate the help.
just to clarify, then the answer would be
(.3636*.3)+(.6363*.6)=0.49
is this right?

bobpursley,
correct.
