Use the data in the following table, which summarizes blood groups and Rh types for randomly selected subjects. Assume that subjects are randomly selected from those included in the table.If one person is selected, find the probability of getting someone who is Group A or type Rh+. Are the events of selecting someone who is Group A and the event of someone who is type Rh disjoint events? The probability of getting someone who is Group A or type Rh+ is...

An experiment on memory was performed, in which 16 subjects were randomly assigned to one of two groups, called "Sentences" or "Intentional". Each subject was given a list of 50 words. Subjects in the "Sentences" group were told to form multiple sentences, each using at least two words from the list, and to keep forming sentences until all the words were used at least once. Subjects in the "Intentional" group were told to spend five minutes memorizing as many of...
