Answer:
8,840
Step-by-step explanation:
Multiply 4420 by 200% to get the answer 8840. You can also multiply 4420 by 2 to get the same answer as you would multiplying by 200%.

Answer:
0.0025 = 0.25% probability that both are defective
Step-by-step explanation:
For each item, there are only two possible outcomes. Either they are defective, or they are not. Items are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
5 percent of these are defective.
This means that 
If two items are randomly selected as they come off the production line, what is the probability that both are defective
This is P(X = 2) when n = 2. So


0.0025 = 0.25% probability that both are defective
Answer:
I think 1/4
Step-by-step explanation:
So, you first should find a common denominator so you can add the fractions together.
So, 1/4 + 1/3 + 1/6 becomes 3/12+4/12+2/12.
Add that up, you get 9/12.
Simplify.
9/12 = 3/4
3/4 is how much is dug out. 4/4 - 3/4 is 1/4. That's how much for digging is left, I believe.
