Answer:
The system has infinitely many solutions
Step-by-step explanation:
we have
----> equation A
----> equation B
Multiply by -2 both sides equation A

----> equation C
Compare equation B and equation C
The equations are identical (is the same line)
therefore
The system has infinitely many solutions
Is a consistent dependent system
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%.
