Answer:
0.0467
Step-by-step explanation:
Probabilty of being defective is [tex]\frac{3}{190}[/tex]
So probability of being good is [tex]\frac{187}{190}[/tex]
Now,
Probability that all 3 of them are good is:
[tex]\frac{187}{190}^{3}=0.9533[/tex]
Now, to find probability of rejection, we subtract the now found probability from 1. Thus, we have:
1 - 0.9533 = 0.0467
