Answer:
0.097 is the probability that the entire batch will be rejected
Step-by-step explanation:
The total number of CDs = 6500
Number of defective CDs = 110
Number of good CDs = 6500-110 = 6390
Out of this batch, 6 are randomly selected, then the probability that the entire batch is rejected is
1 – [probability of accepting the entire batch]
1 – [6390/6500 * 6389/6499*6388/6498*6387/6497*6386/6496*6385/6495]
= 0.097
Can't see question properly. Whats the power on the second number?
All you have to do is divide the score by how many questions there are.
Score = 36
Total = 50
36 ÷ 50 = 0.72
0.72 = 72%
Answer = 72%
Hope this helped :)
