Question??
Dr. Sox drives through two stoplights on her way to work. The first light is green for 20 seconds out of each minute. The second light is green for 35 seconds out of each minute. What is the probability that Dr. Sox will hit two green lights?
Explanation;
Since this is an AND situation, we MULTIPLY the probabilities.
Answer/Explanation:
First light green:
P
1
=
20
60
=
1
3
Second light green:
P
2
=
35
60
=
7
12
Both lights green:
P
=
P
1
×
P
2
=
1

×
7
12
=
7
36
Of course, this is assuming that there is no "green wave" policy, or the two probabilities would not be independent
A. 4/9
b. 3/4
c. 9/3
d. 2/9
e. 1/1

The distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.
<u><em>Explanation</em></u>
According to the diagram, length of the ramp is, 
inches. The top of the seat cushion is 28 inches above the floor. That means, 
inches
We need to find the distance from the base of the ramp to the base of the sofa which is 
In right angle triangle 
, using Pythagorean theorem...
So, the distance from the base of the ramp to the base of the sofa rounded to the nearest tenth is 47.3 inches.
