Asurvey 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.
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.
