Answer:
The probability of selecting a non-defective part provided by supplier A is 0.807.
Step-by-step explanation:
Let <em>A</em> = a part is supplied by supplier A, <em>B</em> = a part is supplied by supplier B and <em>D</em> = a part is defective.
<u>Given</u>:
P (D|A) = 0.05, P(D|B) = 0.09
A supplies four times as many parts as B, i.e. n (A) = 4 and n (B) = 1.
Then the probability of event <em>A</em> and <em>B</em> is:
Compute the probability of selecting a defective product:
The probability of selecting a non-defective part provided by supplier A is:
Thus, the probability of selecting a non-defective part provided by supplier A is 0.807.
0.8/10 = x/100
Cross multiply.
100x = 800
x = 8
Cross multiply.
100x = 800
x = 8
