Add the fractions that chose fish fingers and burgers, then subtract that sum from 1.

Fish fingers: 2/5

Burgers: 1/3

Sum of fish fingers and burgers fractions:

2/5 + 1/3 

Common denominator = 15

2/5 * 3/3 + 1/3 * 5/5 = 6/15 + 5/15 = 11/15

Now we subtract 11/15 from 1.

1 - 11/15 = 1/1 * 15/15 - 11/15 = 4/15

The fraction that chose chicken nuggets is 4/15.
