Step-by-step explanation:

Given that

The probability that a new car of a particular make will have a brake failure is given in the table.

Car MakeBrake Failure

in New Car

A0.0065%     =0.000065

B0.0037%     =0.000037

C0.0108%     =0.000108

D0.0029%    =0.000029

E0.0145%      =0.000145

Total0.0048%  =0.000048

While all cars show the good picture of almost very less probability of brake failure, out of these 5 cars, minimum is that of D

D is more likely to have the very least number of brake failures out of the 5 given

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
