A study found that 27% of the fish in a river are trout, 36% are salmon, and 18% are sturgeon. If a large fish trap is set and it captures 216 fish, how many of those fish are likely to be fish types other than the ones mentioned?

1 answer

27 + 36 + 18 = 81%

100 - 81 = 19% are not those fish

0.19 * 216 = ?
