A track and field team has 48 male athletes and 36 female athletes. At present, a sample with a capacity of 35 is selected by stratified sampling, and female athletes are selected.

This track and field team has 48+36=84 people.

Samples with a capacity of 35 were taken from all the athletes of the team by stratified sampling.

The probability of each individual being drawn is 35.84 = 512.

There are 36 female athletes in the track and field team.

∴ Female athletes should draw 36× 5 12 = 15.

So the answer is: 15.
