In a cookie jar, there are $$6$$ chocolate chip cookies and $$8$$ oatmeal cookies. Hungry Paddy takes out the cookies one at a time and proceeds to eat them. The probability that the $$7^{\mbox{th}}$$ cookie that Paddy eats is a chocolate chip cookie is $$\frac {a}{b}$$, where $$a$$ and $$b$$ are positive coprime integers. What is the value of $$a+b$$?
