If a group of 18 patients is randomly selected, what is the probability of observing, at most, one patient who will be cured of cervical cancer? A 18/1 choose 1(0.30)1(0.70)17 B 1 − 18/1 choose 1(0.30)1(0.70)17 C 18/0 choose 0(0.70)18 D 1 − 18/0 choose 0(0.70)18 E 18/0 choose 0(0.70)18 + 18/1 choose 1(0.30)1(0.70)17
