Answer: The probability that both televisions work is 0.5625 .
The probability at least one of the two televisions does not work is 0.4375.
Step-by-step explanation:
Given : Number of televisions received in shipment= 12
Number of defective televisions received in shipment= 3
Then proportion of defective televisions =![\dfrac{3}{12}=0.25](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B12%7D%3D0.25)
Using binomial probability formula, the probability of getting success in x trials is given by :-
![P(x)=^nC_xp^x(1-p)^{n-x}](https://tex.z-dn.net/?f=P%28x%29%3D%5EnC_xp%5Ex%281-p%29%5E%7Bn-x%7D)
If two televisions are randomly selected, then the probability that both televisions work will be :-
![P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625](https://tex.z-dn.net/?f=P%280%29%3D%5E2C_0%280.25%29%5E0%280.75%29%5E2%3D%280.75%29%5E2%3D0.5625)
The probability at least one of the two televisions does not work will be :-
![P(x\geq1)=1-P(0)=1-0.5625=0.4375](https://tex.z-dn.net/?f=P%28x%5Cgeq1%29%3D1-P%280%29%3D1-0.5625%3D0.4375)
Answer:
Trees can help stop erosion by managing runoff. Their leaf canopies help reduce erosion caused by falling rain. They also provide surface area where rain water lands and evaporates. Roots take up water and help create conditions in the soil that promote infiltration.
