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,

#1) so if the ratio is 2/3 and the other fraction is 16/?, all you have to do is figure out what it took to get there. For example, if the beginning fraction is 2/3 and the second one is 16/?, we at least know that 2 times 8 is 16, so all we have to do is multiply 3 times 8 to get the bottom number which is 24. So 24 is the amount of tan tiles they will need.
(I’ll comment the next two answers)
The degree of a polynomial is the highest power.
In the polynomial we are given, the only power is 2 which makes it greatest.
Therefore, the degree is 2.
Best of Luck!
x is greater than or equal to 6 so 5 and below are not a solution to this inequality.
So check the picture below
if we check the solutions or zeros for the equation, we get

and as you can see in the picture, the value of "x" when y = 3.5, or the height of the truck is

the truck, ends up with a clearance of

on either side, so, the maximum clearance, the truck can have, those two clearances added together,
