(b) What is the probability that the mumber of hits exceeds the mean mumber of hits by more than 2 standard deviations during a four day period?

It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
