Heres another calculation question that I need help with if anyone knows.

I am trying to figure out ratio's or percentages or idk what lol.

If I have...

24 trades total
9 good trades
15 bad (13 were actual loss and 2 should have been but I closed with a slight profit)

how do I figure out the ratio of good to bad trades? Please provide the formula for me to use to figure it out myself!

again I feel so stupid for asking lol, I feel its definatley something I should already know but I dont so I need a lil help...

thanks everyone!
