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 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. which statement is true about whether a and b are independent events? a and b are independent events because p(a∣b) = p(a) = 0.18. a and b are independent events because p(a∣b) = p(a) = 0.4. a and b are not independent events because p(a∣b) = 0.4 and p(a) = 0.18. a and b are not independent events because p(a∣b) = 0.18 and p(a) = 0.4.
