so this is in n my word but I believe ... the low chance of something that was almost certainly going to happen... you can rephrase or change it in your own words, I hope this helped give the close definition of that phrase
If you want to get a reader's attention you would might like to use a sentence that has purpose or something that can suprise the reader and interest them to read deeper,
like:the ice melts quickly on the river over the warm dry sun...
