Hence, statement for survey of children which is true about whether A and B are independent events or not is A and B are not independent events because,
[tex]P(A|B) = 0. 18 \\P(A) = 0. 4.[/tex]
What is the independent event?
Independent events are those events whose occurrences does not depends on the other events.
A survey was taken of children between the ages of 3 and 7. Let A be the event that the person has 2 siblings, and let B be the event that the person does not have a pet. A 6-column table has 3 rows.
The table for the survey is given as,
- The first column has entries has a pet, does not have a pet, total.
- The second column is labeled 0 siblings with entries 29, 31, 60.
- The third column is labeled 1 sibling with entries 84, 45, 129.
- The fourth column is labeled 2 siblings with entries 27, 18, 45.
- The fifth column is labeled 3 or more siblings with entries 10, 6, 16.
- The sixth column is labeled Total with entries 150, 100, 250.
Here, A is the event that a person has 2 siblings, and the B is the event, that a person does not have pet.
As, A and B are independent events then,
[tex]P(A|B)=P(A)[/tex]
Here, the values we have,
[tex]P(A|B) = 0. 18 \\P(A) = 0. 4.[/tex]
Thus, the statement which is true about whether A and B are independent events or not is A and B are not independent events because P(A∣B) = 0. 18 and P(A) = 0. 4.
