Answer:
Binomial
There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.
Step-by-step explanation:
For each copy of the document, there are only two possible outcomes. Either it is defective, or it is not. This means that we can solve this problem using the binomial probability distribution.
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 combinatios of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
In this problem
Of the 20 copies, 2 are defective, so
.
What is the probability that you will encounter neither of the defective copies among the 10 you examine?
This is P(X = 0) when
.

This is volume of a sphere.
Answer:
75
Step-by-step explanation:
Jim will finish in 6 days because 300/50=6
So you know that Sam needs to finish the book in at exactly 4 days
300/4= 75 pages per day
Answer:

Step-by-step explanation make a square on a paper make 3 line on top of each line put 800 40 and 9 on the side put 15 search up 15 dived by 800 and 40 dived by 15 then 9 add it all up the yo go give me brainlist
He biked 1 5/6 miles on Wednesdays which is more than the others. The order for the most to least would be as follows....
Wednesday: 1 5/6 miles
Monday: 1 4/6 miles (this can be simplified to 1 2/3)
Tuesday: 1 3/6 miles( this can be simplified to 1 1/2)
Thursday: 1 2/6 miles (this can be simplified to 1 1/3)
