You roll a six-sided number cube and flip a coin. what is the probability of rolling a number less than 3 and flipping heads? write your answer as a fraction in simplest form.

There's 6 sides on a cube and 2 sides on a coin. You're only trying to find 3, so the answer for the dice is 1/6 and the answer for the coin is 1/2 because it's a 50/50 chance to get heads or tails.

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.
