Answer:
Probability will be 0.0286 which is nit given in the bellow option
So none of the given option is correct
Explanation:
We have given that company receives equipment from company A is 38 %
So [tex]p(A)=0.38[/tex]
And rest of the equipment is received from company B
So [tex]p(B)=1-0.38=0.62[/tex]
It is given that the equipment which is received from company A is 1 % defective
So [tex]p(D/A)=0.01[/tex]
And equipment which is received from company B is 4 % are defective
So [tex]p(D/B)=0.04[/tex]
So the probability that the equipment is defective [tex]=p(A)\times p(D/A)+p(B)\times p(D/B)=0.38\times 0.01+0.62\times 0.04=0.0286[/tex]
So none of the option is correct
