Question

an article manufactured by a company consists of two parts a and b in the process of manufacture of partA , 9 out of 100 are likely to be defective similarly or 5 out of 100 are likely to be defective in manufacturing half part b calculate the probability that the Assembly part will not be defective

Answer 1

Answer:

1729/2000  = 0.8645

Step-by-step explanation:

Probability of Defective Part a = 9/100

Probability of non defective of a = 1 - 9/100 = 91/100

Probability of Defective Part b = 5/100 = 1/20

Probability of non defective part b =  1 - 1/20  = 19/20

Assembly will not be defective if both part are non defective

= (91/100) * (19/20)

= 1729/2000

= 0.8645
