Answer:
a) P(X∩Y) = 0.2
b) 
= 0.16
c) P = 0.47
Step-by-step explanation:
Let's call X the event that the motorist must stop at the first signal and Y the event that the motorist must stop at the second signal.
So, P(X) = 0.36, P(Y) = 0.51 and P(X∪Y) = 0.67
Then, the probability P(X∩Y) that the motorist must stop at both signal can be calculated as:
P(X∩Y) = P(X) + P(Y) - P(X∪Y)
P(X∩Y) = 0.36 + 0.51 - 0.67
P(X∩Y) = 0.2
On the other hand, the probability that he must stop at the first signal but not at the second one can be calculated as:
= P(X) - P(X∩Y)
= 0.36 - 0.2 = 0.16
At the same way, the probability 
that he must stop at the second signal but not at the first one can be calculated as:
= P(Y) - P(X∩Y)
= 0.51 - 0.2 = 0.31
So, the probability that he must stop at exactly one signal is:
Answer:
this is how u solve this
Step-by-step explanation:
Total number of cubic inches of cheese sauce in container = Volume of cylinder = 
Option A is correct.
Step-by-step explanation:
The diameter of cylinder = 16 inches
The height of cylinder = 7 inches
Total number of cubic inches of cheese sauce in container = Volume of cylinder = ?
The formula used to find Volume of cylinder is:
We are given diameter of cylinder while we need radius according to formula.
So, radius = diameter/2
radius = 16/2
radius = 8
Putting values and finding volume:
So, Total number of cubic inches of cheese sauce in container = Volume of cylinder =
Option A is correct.

area = (l)(w)(h)
24 = 4(3 + b)
24 = 12 + 4b
-12 on both sides
12 = 4b
/4 on both sides
b = 3 inches
Substitute b = 3 inches in width
3 + b
3 + 3 = 6 inches
Answer:
width = 6 inches
