I came up with d and e as an answer
Answer:
It would cost <em>n</em> people $<em>nd</em> to play Decimal Decisions and $<em>nr</em> to play Ratio Rage. So, it would cost <em>n</em> people $<em>nd</em> + $<em>nr</em>= $2<em>n</em>(<em>d</em> + <em>r</em>).
<em>d</em>= Decimal Decisions and <em>r</em>= Ratio Rage
You didn't give a price for either game, so I just did variables in place of actual cost. Hope this helps!
Answer:
The answer is 8.3 bar notation.

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.

Answer:
$3
Step-by-step explanation:
Started with $20 Sold for $24 Bought it for $25 Then sold it for $28
