|p|+p=0
=>|p|=-p
It is true when p0,
as 4 numbers satisfy the above condition
so the probability is 4/7
Please approve the solution to encourage me.

This will occur when p is negative or when p=0.
Therefore the required probaility is 4/7, since out of the seven numbers, only -3, -2, -1 and 0 satisfy the condition.
