What is the maximum number of times two planes can intersect? what is thr minimum number of times they can intersect?

Technically, they intersect infinite times if laid perfectly on top of one another. So infinity is the maximum. Then you can have 2 planes running parallel to each other, so they won't intersect at all. So 0 is the minimum.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
