A study on the opinion of the dicoradores regarding the most desirable primary color for use in executive offices showed the following results:
Primary color
Number of decorators
Red
92
Orange
86
Yellow
46
Green
91
blue
37
Indigo
46
Violet
two
What is the probability that a decorator does not prefer blue?
a. 0.8850
b. 0.9075
c. 0.7725
d. 1.000
Homework Answers
| Red | 92 |
| Orange | 86 |
| Yellow | 46 |
| Green | 91 |
| Blue | 37 |
| Indigo | 46 |
| Violet | 2 |
| Total | 400 |
The total number of decorators are 400.
Blue decorators are 37
P( Prefer blue) = 37/400 = 0.0925
The probability that a decorator does not prefer blue = 1 - P(Prefer blue) = 1 - 0.0925 = 0.9075
b. 0.9075

Using C++ COLOR MIXER- The color red, yellow, and blue are primary colors because they cannot be made by mixing other colors. When you mix 2 primary colors you get the following: When you mix red and blue, you get purple. When you mix red and yellow, you get orange. When you mix blue and yellow, you get green. Write a program to ask the user for 2 primary colors (an error if they are not primary). Then display the...

Now rank each visible light color of the rainbow by how much ENERGY is carried by its photons, ranking them from highest energy to lowest energy. If you answer incorrectly and need to change the order of your options, drag one item until it is directly on top of a second item. This will force the second item back into the sorting queue on the left, and open a blank space on the right with which you can re-order your...
