5 out of 60 numbers 1 to 60 + 1 from 1 to 25. How many combinations is possible?
I think (this is without replacement and order does not count.)
60C5*25C1= 60C5*25
$${\left({\frac{{\mathtt{60}}{!}}{{\mathtt{5}}{!}{\mathtt{\,\times\,}}({\mathtt{60}}{\mathtt{\,-\,}}{\mathtt{5}}){!}}}\right)}{\mathtt{\,\times\,}}{\mathtt{25}} = {\mathtt{136\,537\,800}}$$
