which statement is true about whether a and b are independent events?

a) a and b are independent events because p(a∣b) = p(a) = 0.18.
b) a and b are independent events because p(a∣b) = p(a) = 0.4.
c) a and b are not independent events because p(a∣b) = 0.4 and p(a) = 0.18.
d) a and b are not independent events because p(a∣b) = 0.18 and p(a) = 0.4.
