Question 1193213
mean is np=10*0.06=0.6
variance is np(1-p)=0.6*0.94=0.504
sd is sqrt (V)=0.701
-
0 are fraudulent mean that 10 are not=0.94^10=0.5386
-
1 is fraudulent is 10C1*0.06*0.94^9=0.3438
The sum of p(0) and p(1) is 0.8824
>=2 is 1- the above sum or 0.1176, the answer
-
4 will own is 7C4*0.52^4*0.48^3=0.2830
no one will is 0.48^7=0.0059
1 will is 7C1*0.48^1*0.52^6=0.0664
the last two sum to 0.0723
the complement is probability 0.9277, and that is 2 or more, the answer.
