Answer:
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
Step-by-step explanation:
Given that:
Total Number of cameras (n) = 8
Defective cameras = 4
X: number of defective cameras
For a binomial distribution :
P(x) = nCx * p^x * (1 - p)^(n - x)
Probability of success (p) on each trial is the same = (total number of samples / number of defective samples) = 8/4 = 0.5
If 2 samples are chosen at random :
Then, the binomial probability distribution will be :
P(x) = 8Cx * p^x * (1 - p)^(8 - r) ; r = 0, 1, 2
I’m not 100% but I think it could be the last table
Answer:
6(37.5) + 45 = $270
Step-by-step explanation:
Answer:
If the customers will still buy it, why not?
If a storekeeper buys an item from a supplier for $10.00, and sells it for $20.00, the markup would be 200%.
* * * * *
Not true.
The value of the mark up in the above example is $10.00 which, given a cost of $10.00, is a 100% mark up. A 200% mark up of an item costing $10.00 would entail a "profit" of $20.00 giving a total price of $30.00
