Problem Inputting Formula Into Wolfram Alpha

Question

I am trying to calculate the following:

$1-\sum_{k=0}^4\frac{\binom{2,500}{k}\binom{247,500}{8,500-k}}{\binom{250,000}{8500}}$

I am inputting this into wolfram alpha like this but I can't seem to get the formula correct.

Answer 1

you just need to add a space after the commas as:

1-sum[binom[2500, k]*binom[247500, 8500-k]/binom[250000, 8500],{k,0,4}]
