If P(X < a) = b then is P(f(X) < f(a)) = b?

My intuition says it's true but I cannot prove the case nor find the name of the theorem. mathematical-statistics function measure-theory share | cite | improve this question asked 1 hour ago Linsu Han 6 2 By "monotonic increasing" do you mean strictly increasing (if $a ...

No Video Signal on boot

Image
up vote 1 down vote favorite 2 Trying to troubleshoot a no video signal issue. Running Ubuntu mate 18.04 LTS. When trying to boot this evening was getting no video signal I have dual Titan Volta GPU's and tried switching the HDMI cable to the 2nd GPU. No difference. Not getting any error messages on the motherboard on boot. I know my monitor is fine because I can plug my laptop into the 2nd HDMI input. Never experienced this before. Is it possible either a recent software and or driver update has hijacked the video out signal? Is there some keyboard combination I can try on boot? Any feedback welcome! video-driver share | improve this question edited Dec 5 at 15:...
