Aluminum usage in automobiles has been climbing steadily. As recently as 1990, there were no aluminum-structured passenger cars
lara [203]

Answer:

P(A U B)= 0.08

Step-by-step explanation:

1.Let:

P(A) as the probability that a psiton has an under-fill defect

P(B) as the probability that a pistón has a porosity defect

P(A ∩ B) the probability of having both defectos

Then:

P(A)=0.05

P(B)=0.04

P(A ∩ B)=0.01

2. The probability that a randomly chosen piston has a defect could be calcularse as the union of the probability of choosing a piston with am under-fill defect and one with porosity defect.

That Is P(A U B)

Aplying the probability properties we have:

P(A U B)= P(A) + P(B) -P(A ∩ B)

Replacing the probabilities:

P(A U B)= 0.05+0.04-0.01

P(A U B)= 0.08

VashaNatasha [74]

Answer:

163.3

Step-by-step explanation:

3.14*r^2*h

h=13

4/2 = 2

r=2

2^2 = 4

3.14*4 = 12.56

12.56*13 = 163.28

Rounded = 163.3

I believe the answer is 163.3
