Acomputer randomly selects a number from the given set.

{2, 4, 6, 9, 16, 44, 51, 60, 78}

what is the probability that a number less than 10 is selected?

The probability of the computer selecting a number less the ten is 44.4% or 4/9.

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.
