in volleyball, you can volley, set, or spike.how many ways can your team make two plays? use tree diagram. thanks

Question

Draw three "branches" for the first play, then three branches from each of them for the second "play" for a total of nine. However, two consecutive spikes without a set is not likely to happen. Nor are two consecutive sets. It all depends upon what you call a "play", and whether they involve consecutive hits.

This seems to me a confusing way to teach statistics or math.

Two consecutive sets are indeed possible. I seem to have have forgotten the rules of volleyball. Anyway, I think the answer they expect is 9

thank you
