a. The events are mutually exclusive, so
b. For the same reason,
Another way to see this is to use the result from part (a), and the inclusion/exclusion principle:
and the right side reduces to 0.
c. Same as (b),
d. Same as (b),
We can also use the distributivity rule for unions and intersections to write
e. If the 
is the complement of 
, then by DeMorgan's law,
Answer:
volume=l×b×h=8.2×3.7×4.1=124.394in³
I think it’s y=3x-1
I may be wrong but at least I tried
Add 42.6 and 28.5 to get 71.1 feet of chicken coop wire
We'll start with the expression for the quotient of 
and 
, which means we'll use division:
Now we find 
less than that, meaning we'll use subtraction:
