Answer:
the first graph does////=//
So first of all, find d. It is the only letter you can be sure of because all of them are the same. So 3d = 9. Divide by 3 to get d = 3. Now 2C + 3 = 21, because there are 2 C's in the bottom row. Subtract 3 from both sides to get 2C = 18. Divide by 2 to get C = 9. 2C + A = 21, or 18 + A = 21. Subtract 18 from both sides to get A = 3. A + B + C = 14, or 3 + B + 9 = 14. Combine like terms to get 12 + B = 14. Subtract 12 from both sides to get B = 2. So A = 3, B = 2, C = 9, and D = 3.

I need help too with this. I don’t understand it in the least.
Using Venn probabilities, it is found that there is a 0.03 = 3% probability of a chain defect.
<h3>What is a Venn probability?</h3>
In a Venn probability, two non-independent events are related to each other, as are their probabilities.
The "or probability" is given by:
In this problem, the events are:
Event A: Brake defect.
Event B: Chain defect.
For the probabilities, we have that:
- The study finds that the probability of a brake defect is 4 percent, P(A) = 0.04.
- The probability of both a brake defect and a chain defect is 1 percent, P(A∩B) = 0.01.
- The probability of a defect with the brakes or the chain is 6 percent, P(A∪B) = 0.06.
Substitute all the values in the formula
0.03 = 3% probability of a chain defect.
Hence, there is a 0.03 = 3% probability of a chain defect.
