What is the meaning of ようじゃね?


I didn't understand " **ようじゃね** " in this sentence.

大チャンスで ２分の１をはずす **ようじゃね**




> 大チャンスで2分の1をはずすよう **じゃね** 。  
>  _**If**_ he fails to grab this great opportunity and loses a 50-50 bet... _
> **you know**_.

This ようじゃ is a colloquial way of saying [ようでは](https://jlptsensei.com/learn-
japanese-grammar/%E3%82%88%E3%81%86%E3%81%A7%E3%81%AF-you-dewa-meaning/) ("if
something/someone is like ～"). ね is a filler particle, but it's probably
working like "you know (what I mean)" here. It depends on the context, but
usually something like "he was doomed to fail in the first place" is implied.
