two people have bags of 60 marbles, each numbered 1 though 60.
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 can't figure that out.
