Let "p" is ""x< 50" "; "q" is ""x> 40" ". Let us express the following compound propositions as English sentences in a natural way:


(a) "\\neg p" : "x is greater than or equal to 50"


(b) "\\neg q" : "x is less than or equal to 40"


(d) "p\\lor q" : "x is less than 50 or x is greater than 40"


(e) "\\neg p\\lor q" : "x is greater than or equal to 50 or x is greater than 40" which is equivalent to "x is greater than 40"


(f) "\\neg p\\lor \\neg q" : "x is greater than or equal to 50 or x is less than or equal to 40"
