SOMEONE WHOS GOOD AT EXPLAINING WITH FULL DETAILSSo here we have this fully answered probability tree as an example.How am I suppoused to answer this from scratch. Like, how do I get the percentages? Better yet, how do I start and how do I finish this?Please help guys.

Im not sure what you are asking, but for a probability tree, you have the total # of something at the very top of the tree, next it branches out into groups, and those groups represent something like colored marbles or something... and to find percent you divide the total number like the number of marbles bye 100 and multiply that number bye the thing that you're trying to get job percent like a color of marbles, I hope this helped...
