Document Summary

Atree diagrams haspoints and branches edges the starting point is called a root terminalpoint a pointfromwhichtherearenomore branches tofollow. Path starts attherootandends at a terminalpoint can beused to represent a sequenceofdecisions which mustbemade. Cab feare home from the pub is . 5, and you add a tip. Each di erent level of branching corresponds to a di erent subset (or characteristic) A counting has the number of elements in the subset of the corresponding branch. Branches grow from an earlier branch correspond to intersections of subsets. Each element of the universal set, u, starts at the root, and follows the branches that describe that element. the # of brance = to #of elements that travels on that branch. Lake field music is a camp for amateur musicians. Everyone who comes to camp call participants sings or plays an instrument, and many do both. In total, there were 75 who sing ,40% of who were new.
