Answer: a) 50% , and b) 50%.
Step-by-step explanation:
Since we have given that
P(A) = 41%
P(B) = 9%
P(AB) = 4%
P(O) = 46%
Since antigen A or antigen B are independent events.
So, P(A ∪ B) = P(A) + P(B)
Probability neither the A nor the B is given by
Hence, a) 50% , and b) 50%.

Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
