Just multiply the two numbers, then add a negative sign.
2 x 3 =6
3 x 1 =3
6/3=2
2/3 x -3 = -2

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

the unit price per pound is $3.45
Answer:
Both prices should be set to #25.
The maximum revenue is #4375
Step-by-step explanation:
Given
Start by calculating the total revenue (R):
Collect and solve like terms
Differentiate with respect to pi and to p2, respectively
Equate both to 0, to get the critical point
Solve for p1 in
Substitute in
Substitute in
So, we have:
This implies that the prices should be set to #25.
The maximum possible revenue is:
The maximum revenue is #4375
