What is probability?

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

A random sample of students was asked whether they preferred to sweep the floor or to do the dishes, and whether they preferred to hear music or have silence while doing the chore.

The results of the survey are summarized in the table.

                      Sweep              Dishes             Total

Music                36                     60                   96

Silence              42                    62                   104

Total                  78                    122                  200

Then the probability that a student prefers to do the chore in silence will be

P = 104 / 200

P = 0.52

Thus, the correct option is E.
