two people have bags of 60 marbles, each numbered 1 though 60.(adsbygoogle = window.adsbygoogle || []).push({});

each pulls 20 marbles...what is the probability that they match at least one number.

the way i did was figure out what are the chances they match none and subtract that from 1:

1 - [(40/60)(39/59)(38/58)...(22/42)(21/41)]

is that correct?

now what if it was match at least 10 numbers...i cant figure that out.
