a survey asks teachers and students whether they would like the new school mascot to be a shark or a moose . this table shows the results .
a person is randomly selected from those surveyed
are being a student and preferring “shark” independent events ? why or why not ?

Being a student and preferring “shark” are not independent events

Step-by-step explanation:

Let A be the event that the selected person is a student and B the event that person prefers sharks.

Total number of students =100

Hence P(A) =

P(B) = Persons who prefers sharks /total persons

=

P(AB) = no of persons who are students and who prefer sharks/total persons

=

P(A)P(B) =

Since P(AB) does not equal P(A) P(B), we find that

A and B are not independent.

Being a student and preferring “shark” are not independent events
