Answer:
C
Step-by-step explanation:
3x-y=14
4x+y=21
add
7x=35
x=35/7=5
4×5+y=21
y=21-20=1
so (5,1 ) is the solution.
Answer:
0.96% probability that the 5th item inspected is the first defective item found
Step-by-step explanation:
We have these following probabilities:

99% probability that an item is not defective.
What is the probability that the 5th item inspected is the first defective item found?
First four not defective, with a 99% probability.
Fifth defective, with a 1% probability. So

0.96% probability that the 5th item inspected is the first defective item found
The step by step multiplication is performed and shown below:
