Answer: 175 defective bulbs.
Step-by-step explanation:
1. Keeping on mind that the inspector examined 100 light bulbs and found 7 defective, you can calculate the number of defective bulbs that there would be in a lot of 2500 bulbs as following:
- Let's call the number of defective bulbs that there would be in a lot of 2500 bulbs 
.
- Then, you have:
- Solve for x:
2. Then, there would be 175 defective bulbs in a lot of 2500 bulbs.
Answer:
x=8
Step-by-step explanation:
3(x+4)=36
Divide each side by 3
3/3 (x+4)=36/3
x+4 = 12
Subtract 4 from each side
x+4-4 = 12-4
x = 8
You have to do 225 plus 125 divided by 2 times 100 and that is your percent
Answer: 4
Step-by-step explanation: Range is the difference between the highest and lowest number, so since 5 is the highest and 1 is the lowest you subtract 1 from 5 to get your answer: 4.

What is the meaning of probability in math?
- Probability is simply how likely something is to happen.
- Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
- The analysis of events governed by probability is called statistics.
Three Types of Probability
- Classical: (equally probable outcomes) Let S=sample space (set of all possible distinct outcomes).
- Relative Frequency Definition
- Subjective Probability.
