Question 931620
p(stolen) = .20,  n = 4
p(not stolen) = .80
......
E(x) = .2(4) = .8
P(x = 0) = .8^4
P(x = 2) = 4C2(.2^2)(.8)^2  0r binompdf(4, .2, 2) = .1536  0r 15.36%
......
Re TY
to find .1536
either calculate: 4C2(.2^2)(.8)^2
Or  Use a TI calculator 0r similarly a Casio fx-115 ES plus for: 
binompdf(4, .2, 2)
