To find f(2), you just need to replace x for 2.
1/3•4^(2)
The answer is 16/3 or 5.3333...
Answer:
We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

For this case we have that:

And we see that 
So then we can conclude that the two events given are not independent and have a relationship or dependence.
Step-by-step explanation:
For this case we can define the following events:
A= In a certain computer a memory failure
B= In a certain computer a hard disk failure
We have the probability for the two events given on this case:

We also know the probability that the memory and the hard drive fail simultaneously given by:

And we want to check if the two events are independent.
We need to remember that we have independent events when a given event is not affected by previous events, and we can verify if two events are independnet with the following equation:

Answer:
16pi cm2
Step-by-step explanation:
Area of a circle = pi * radius * radius = pi * 4 cm * 4 cm = 16pi cm2
