Step 1
Given Information:
In a survey conducted to see how long Americans keep their cars, 2000 automobile owners were asked how long they plan to keep their present cars.
To find the probability distribution associated with these data:
Years Car Is Kept, xRespondentsProbability0x<155552000=0.02751x<34304302000=0.2153x<53153152000=0.15755x<73453452000=0.17257x<102452452000=0.122510x6106102000=0.305Total20001
Step 2
To find the probability that an automobile owner selected at random from those surveyed plans to keep his or her present car:
(a) Less than five years:
Required probability is obtained as follows:
P(Les that 5 years)=0.0275+0.215+0.1575
=0.4
b) 3 years or more:
Required probability:
P(3years or more)=0.1575+0.1725+0.1225+0.305
=0.7575
