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 .
There is a 34.87% probability that you will encounter neither of the defective copies among the 10 you examine.
The square measures 14 by 14
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
= 19.80 inches (2 d.p.)
so the area = 14 x 14 = 196 square inches
Double the area:
196 x 2 = 392 square inches
To find one side of the square:
