Step-by-step explanation:
im not positive but it should be 12% chance that one is defective and then 11% chance when you pull one out
Answer:
Time to serve the customer arriving at 10 a.m. = T × (Demand/Capacity - 1)
2 * (100/80 - 1) = 0.5
The customer arriving at 10 a.m. would have to wait 0.5 hours to be served.
Step by step:
3 x 9/10
Turn 3 into a fraction
3/1 x 9/10
Now multiply straight across
3x9=27 and 1x10=10
So you get
27/10 or 27/10 or 2.7
This can also be completed by simply turning 9/10 into a decimal and doing
3 x 0.9 = 2.7

Let the nth term of the sequence be 
The given sequence is an arithmetic sequence that has the following common difference (d)



So, the nth term is:

Hence, the recursion is:
where
