Question 307706
This a "capture-recapture" problem. Scientists often use the "capture-recapture" method to determine the number of fish in lake or the number of deer in game preserve, for example.
Original number captured/Total number (x) = Total number tagged/Total number recaptured.
{{{302/x = 162/324}}} Solve for x.
{{{302(324) = (162)*x}}} so...
{{{x = 302(324)/162}}}
{{{x = 604}}}
There are 604 deer in the game preserve.
