Hi There! I am Not the best at Math But I hope this helps.
Lets firstly Cross some people out. Michelle, It's not very Likely for them to be able to Succeed that amount but even so, they'd have to Go through all of them to make sure if A singular one was correct.
Liam Is next to go, As Michelle, His has far too many trials. He'd have to go through each and everyone of them To find the correct one.
It's more or so now stuck between Isaac and Latoya
I hope this somewhat Helped you! Good Luck!
