A conservation biology team monitored the population density of the desert ironclad beetle (Asbolus verrucosus) in a protected arid dune reserve. They employed the mark-release-recapture method.
In the primary sampling session, they captured, marked, and released 848484 beetles.
After allowing a period of six days for the marked individuals to mix thoroughly with the rest of the population, a secondary sample of 757575 beetles was collected from the same dune area. The researchers calculated the total population of desert ironclad beetles in this reserve to be 350350350.
Determine the number of beetles in the second sample that were found to be marked.
