Whereas, I get this one:
Any suggestions for the code I wrote below?

With no additional packages (I am assuming that Comic Sans is not your dream):

documentclassarticle


begindocument

begincenter
begintabularc
multicolumn1c& $A$ &multicolumn1c NOT $A$ &multicolumn1c SUM\
%hline
cline2-4
$B$ & $P(A$ AND$,B)$ & $P($NOT $A$ AND$,B)$ & $P(B)$\
NOT $B$ &$P(A,$NOT$,B)$ &$P($NOT $A,$AND NOT$,B)$ & $P($NOT $B)$ \
%hline
cline2-4
& $P(A)$ & $P($NOT $A)$& $1$\
%hline
cline2-4
endtabular
endcenter

enddocument


This is easy with blkarray:

blkarray

documentclassarticle
usepackage[utf8]inputenc
usepackage[T1]fontenc
usepackagemathtools, blkarray

begindocument

[ everymathdisplaystylesetlengthBAextrarowheight2pt
beginblockarraycccc
& A & textNOT A & SUM\
BAhhline~---
beginblockc
B & P(Atext ANDB) & P(textNOT Atext AND B) & P(B)\
textNOT B &P(Atext NOT B) &P(textNOT Atext AND NOT B) & P(textNOT B) \
BAhhline~
& P(A) & P(textNOT A)& 1\
BAhhline~---
endblock
endblockarray ]

Use multicolumn command to suppress vertical ruling of specific cells. If the table width is not as you want, try to modify the width provided in textwidth

multicolumn

textwidth

documentclassarticle
usepackageamsmath
renewcommandarraystretch1.7
usepackageragged2e
usepackagetabularx
newcolumntypeC > arraybackslash Centering X
usepackagebooktabs
usepackagemakecell

begindocument


noindent
begintable*

begintabularxtextwidth
