p yes broke = .18
p not broke = .82
P(0 broke) = 1*.18^11 * 1
P(1 broke) = C(11,1).18^10 .82^1
P(2 broke) =C(11,2).18^9 .82^2
C(11,1) = 11
C(11,2) = 55
Industry standards suggest that 18% of new vehicles require warranty service within the first year. Jones Nissan, sold 11 Nissans yesterday
What is the probability that less than three of these vehicles require warranty service?

sorry
P(0 broke) = 1* 1 * .82^11
P(1 broke) = C(11,1).18^1 .82^10
P(2 broke) =C(11,2).18^2 .82^9
P(0 broke) = 1* 1 * .82^11
P(1 broke) = C(11,1).18^1 .82^10
P(2 broke) =C(11,2).18^2 .82^9
