Usage
Although it is very common to talk about something being very possible or more possible, these uses are generally thought to be incorrect, since possible describes an absolute state, and therefore something can only be possible or not possible: it is very likely (not very possible ) that he will resign; it has now become easier (not more possible ) to obtain an entry visa
Related Words
Possible, feasible, practicable refer to that which may come about or take place without prevention by serious obstacles. That which is possible is naturally able or even likely to happen, other circumstances being equal: Discovery of a new source of plutonium may be possible. Feasible refers to the ease with which something can be done and implies a high degree of desirability for doing it: This plan is the most feasible. Practicable applies to that which can be done with the means that are at hand and with conditions as they are: We ascended the slope as far as was practicable.

Explanation
Something that’s possible is something that can happen, something that can be done, or something capable of existing. You can use possible to talk about anything that might happen. If you work really hard for a test, and you show you know the material, it’s possible that you’ll get an A. For a really hard problem like inventing a car that doesn’t use gas, you’ll need to pursue many possible solutions. If you write science fiction, you like to imagine possible worlds. Anything is possible, if you just put your mind to it!
