(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
