Answer:

Step-by-step explanation:

Given that a consumer organization estimates that over a​ 1-year period 20​% of cars will need to be repaired​ once, 9​% will need repairs​ twice, and 4​% will require three or more repairs.

No of cars -2

Each car is independent of the other.

Prob that a car does not need repair = 1-0.20-0.09-0.04 = 0.67

a) Prob (neither will need repair) =0.67*0.67=0.4489

b) Prob (both will need repair) =0.33*0.33=0.1089

c) Prob (atleast one will need repair) =1- neither repair

=1-0.4489

=0.5511
