The following problem is an example of the capture-recapture method of population estimation. A researcher wants to estimate the number of rab-bits in a region. The researcher sets some traps and catches 30 rabbits. After the rabbits are tagged, they are released unharmed. A few days later the researcher sets some traps again and this time catches 35 rabbits. Of the 35 rabbits trapped, 5 are tagged, which indicates that they had been trapped a few days earlier. Based on these results, what is the best estimate you can give for the num-ber of rabbits in the region? Solve this problem in three different ways, explaining your reasoning in each case.
