Answer:
9/25 = 36/100 = 36% . . . . "out of" meaning "parts of"
25 - 9 = 16 . . . . "out of" meaning "from"
Explanation:
The wording "out of" can be taken a couple of ways in this usage. Context is important, and no context is provided here.
__
Often, it means "parts of" as in 9 of 25 parts, or 9/25.
An equivalent fraction is 18/50 or 36/100 = 0.36 = 36%.
This would be the usual meaning in the context of probability.
__
This wording can also mean 9 parts taken from 25, so the remaining amount is 16. Equivalents might be 10 from 26, or 4 from 20.
