... So
Can't be true then because if temperature and RPM is high, the warning light is not necessarily on.
yes it isn't true I made a mistake there again :( ...

my part b says to tell those system conditions where pilot will get a warning so whenever I get a HIGH on my output I just need to tell that statement and my part b is done right?

Yes, but the question asks for engine conditions, not sensor output values - so you'll need to give the answer relative to the switching point of each sensor.

like for example : If my Temp is high and P is high and RPM is low than the pilot will get a warning like these :D

No, the question asked for engine conditions, you've given engine sensor logic values.

You need to convert the signal logic to the actual engine condition as in:
RPM sensor output = 0, only when speed < 4800 rpm
• P sensor output = 0, when pressure <220 psi
• T sensor output = 0, only when temperature < 200˚F

hmm like this:

If temp > 200 F and P > 220psi the pilot will get a warning ?

thanks man really appreciate your help :) if you don't mind I'm going to post some more questions here :p as I've got my exam this tuesday hope you'll help :)
Go for it. While I may, or may not, be able to help, there are plenty of people here that are willing to help.

Don't forget parts c and d...
