Someone whos good at explaining with full details so 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?guys.

Step-by-step explanation:

you have the total number of something at the very top of the tree, next it branches out into groups, and those groups represent something like colored marbles or anything u really want... and to find percent you divide the total number like the number of marbles or something by 100 and then * that number bye the thing that you're trying to get job percent like a color of marbles or any item that u used for this example i hope this helpssry if i didnt
