7 white socks anf four black socks are in a bag. if two socks are drawn at random, what is the probability that both socks are the same color?
thank you so much for the help
3 out of 11
i'm sorry, i don't understand this response. does it mean the first answer 3/11 is incorrect?
Pr(both)=Pr(both black) + prob(white)
= 4/11*3/10 + 7/11*6/10
thank you for taking the time to answer my question. i very much appreciate the help.
just to clarify, then the answer would be
is this right?
thank you again for all the help
