NULL == X is just another coding style used by the programmers to avoid some mistakes in codes. 

Whenever people write bigger codes they use to follow these type of convention instead of X == NULL reason being while writing code the programmer may type X = NULL instead of X == NULL which will result in overwriting of X.
While in other case NULL ==X if accidently programmer writes NULL = X then he/she will get a compilation error instead overwriting.

eg: some hashtag says #serious so you can use this type of info in performing your sentiment analysis.

P(8≤X≤28) = P(-10 ≤ (X-18) ≤ 10 ) 

= P((X-18) ≤ 10 ) ≥ 1 - (var / (10)^2) = 1- (6.25 /100 ) =  .9375  ( by chebeshey's inequality)

it shud be D L2 must be regular.

L1 = phi

L2 =(a+b)* union of both is Complete language which is regular

L1= epsilon

L2=a

union of both is also regular but finite

so D

since X is complete language except epsilon so it will cover everything
