Hello, courteous!

For example,__\frac{ 4\choose 4 48\choose 9 }{ 52\choose 13 }__gives this:

The "choose" function must be enclosed in: .{6 \choose 2}*braces*

The code looks like this:

\frac{ {4\choose4} {48\choose9} } { {52\choose13} }

. . .

As Plato pointed out, it can be enlarged

. . by inserting \displaystyle in the numerator and denominator.

\frac{\displaystyle {4\choose4} {48\choose9} } {\displaystyle {52\choose13} }

. . .

It works!

Though I'm pretty sure I tried curly braces around \choose before. (Thinking)

Thank you both. (Happy)
