A medical treatment has a success rate of 0.8. Two patients will be treated with this treatment. Assuming the results are independent for the two patients, what is the probability that neither one of them will be successfully cured.
--------------
P(not cured) = 0.2
-----
P(not cured and not cured) = 0.2*0.2 = 0.04
