In each of the problems below, show the different stages of mathematical modelling for solving the problems. An ornithologist wants to estimate the number of parrots in a large field. She uses a net to catch some, and catches 32 parrots, which she sets free. The following week she manages to net 40 parrots, of which 8 are ringed. : Find an estimate of the total number of parrots in the field.
