Perhaps something like this? (mathematically it is not correct, I just
show how to print the summation)

Grid[{{"P(X=j|n,p)=", Style["\!\(\*UnderoverscriptBox[\"\[Sum]\",
RowBox[{\"j\", \"=\", \"1\"}], \"n\"]\)", Italic, 32], Binomial[n, j],
p^j (1 - p)^(n - j)}}, Frame -> True, Spacings -> {.5, 2},
ItemStyle ->
Directive[FontFamily -> "Tahoma", Bold, 24]] // TraditionalForm
