Answer:
The Venn diagram has 8 different colored areas, in the image attached you can see the colors and the sets that make up the Venn diagram:
1. white:
U / (A ∪ B ∪ C)
2. black:
A ∩ B ∩ C
3. yellow:
A / (A ∩ B) ∪ (A ∩ C)
4. blue:
B / (A ∩ B) ∪ (B ∩ C)
5. red:
C / (B ∩ C) ∪ (A ∩ C)
6. green:
A ∩ B / (A ∩ B ∩ C)
7. orange:
A ∩ C / (A ∩ B ∩ C)
8. violet:
B ∩ C / (A ∩ B ∩ C)
Step-by-step explanation:
Each set has a color, A is yellow, B blue and C red. Taking the notation of sets and the law of combining colors, you can find all the colors that make up the diagram.
1. white: the universal set (U) has all the elements, except for those that are not in the A, B and C sets.
U / (A ∪ B ∪ C)
2. black: this color is formed with the combination of all colors in the diagram, and it contains the intersection of the 3 sets.
A ∩ B ∩ C
For colors yellow, blue and red you can take each set A, B and C and subtract from each one of them the union of the intersection of the other two sets.
3. yellow:
A / (A ∩ B) ∪ (A ∩ C)
4. blue:
B / (A ∩ B) ∪ (B ∩ C)
5. red:
C / (B ∩ C) ∪ (A ∩ C)
Finally, for colors green, orange and violet you take the intersection of each set A ∩ B, A ∩ C and B ∩ C and subtract from them the elements in the black set.
6. green:
A ∩ B / (A ∩ B ∩ C)
7. orange:
A ∩ C / (A ∩ B ∩ C)
8. violet:
B ∩ C / (A ∩ B ∩ C)

Answer:
<h2>72,86 ≈ 73</h2>
Step-by-step explanation:
In this case we can use the normal table in which you must find the value 0.7 (in the inside) and then you should find the corresponding z value. After this you should multiply the z value by the standard deviation and then you must at to it the mean. This way you can get the score.
Another option is to use the function NORM.INV in excel where you must pass as arguments the probability (0.7), the mean (65) and standard deviation (15)
