Twenty five elks live in a certain area of which 6 were tagged and released. A certain time later, 5 elks were randomly caught. Assume all 25 elks were equally likely to be caught. What is the probability that exactly 2 of these 5 elks caught were previously tagged? Do NOT round.

Write your answer as

ans = <some expression>

ans = (6/25)*(5/24)*(4/23)*(3/22)*(2/21)/(5/25)*(4/24)*(3/23)*(2/22)*(1/21)
