Given three identical bags each containing **$$10$$** balls, whose colours are as follows:

Bag I **$$3$$** Red **$$2$$** Blue **$$5$$** Green
Bag II **$$4$$** Red **$$3$$** Blue **$$3$$** Green
Bag III **$$5$$** Red **$$1$$** Blue **$$4$$** Green

A person chooses a bag at random and takes out a ball. If the ball is Red, the probability that it is from Bag I is $$p$$ and if the ball is Green, the probability that it is from Bag III is $$q$$, then the value of $$\frac{1}{p} + \frac{1}{q}$$ is:
