Answer:
Step-by-step explanation:
a. 0.31
You probably know that for 
, we have
Your sum starts at 
, so it's equivalent to
so the answer is A.
A and B are dependent events.
The general probabilities of each event to happen separately is 36% for event A and 25% for event B. When considering that Chris passes one before passing the other, indicates that whether he gets the first light open or not will affect if he gets the other one also open or not. This can even be seen by noticing how the probability of Chris getting both red lights is 9%, a much inferior probability then considering both lights separately which means that one event has influence over the other.

Answer:
17% off $35
Step-by-step explanation:
The reason I say 17% off $35 is better price is because you get $5.95 off the original price.
So how did you do it they wonder, well in order to find out how much we are going to be taking off of a number as a percentage we have to turn 17% and 12% into a decimal by multiplying 17% and 12% by 100.
17% * 100 = 0.17
12% * 100 = 0.12
Now we multiply 0.12 by $32 and 0.17 by $35 in order to find out how much money you are saving:
0.12 * $32 = $3.84
0.17 * $35 = $5.95
So since $5.59 is bigger than $3.84 you have your answer 17% off $35 is a better price.
