In a particular suburb 30% of housholds have installed electronic security systems. If 2 households are chosen at random from this area, what is the probability that neither has installed a security system?
Using the binomial probability function for this problem:
P(x) = (nCx)(p^x)[q^(nx)]
p = .3
q = 1  p = .7
x = 0
n = 2
P(0) = (2C0)(.3^0)(.7^2)
Finish the calculation for your probability.
