70% of residents have reduced their electricity usage sufficiently to qualify for discounted rates. If 5 residential subscribers are randomly selected A. What is the probability that all five qualify for the discounted rates B.find the probability that at least 4 qualify c. Find the probability that most of the residents qualify Show work And please show steps

2. a. (.70)^5 = 0.16807

b. (.70)^4 * (.70)^5 = 0.117649

c. assuming that most = 3

(.70)^3 = 0.343

not sure if right but whatever

n=5
p=0.7
a)
(0.7)^5 = 0.16807

b)
(0.7)^4 * (0.3) * C(5 ,4) + (0.7)^5 = 0.36015 + 0.16807 = 0.52822

c)
(0.7)^3 * (0.3)^2 * C(5,3) + (0.7)^4 * (0.3) * C(5, 4) + (0.7)^5 = 0.3087 + 0.36015 + 0.16807 = 0.83692

EDIT:Before you're confused
C(5,3) =P(3)
C(5,4) =P(4)
