I have this one problem with which I would appreciate help:

A discrete random variable X can take the following values:

0, 1, 2, 3, 4, 5, 6, 7, 8, and 9

Its probability distribution is given by f(x)

0.02, 0.1p, 0.2p, 0.05, 0.1, 0.7p, 0.2, 0.9p, 0.5, 0.3p.

How will I determine the value of p?
 
The sum of these numbers must be 1.
0.02+ 0.1p+0.2p+ 0.05+0.1+0.7p,+0.2+ 0.9p+0.5+ 0.3p=1
