In order to make sense

[Musicgold]

Hi,

The following first sentnece is from a book. #2 is my version. Does #2 sound odd?

1. Many ratios must lie between 0 and 1 in order to make any sense. Probability is one of them.

2. Many ratios must lie between 0 and 1 in order for them to make any sense. Probability is one of them.

Thanks,

MG.
