Here’s how I solved to find the area. Hope this is helpful
Answer: 8
Step-by-step explanation:
4 is the base. 8 are the sides
Is 12 because is the same size as the other one ....
Using the hypergeometric distribution, it is found that there is a 0.1667 = 16.67% probability that he selects the two good batteries.
The batteries are chosen from the sample without replacement, which is why the <u>hypergeometric distribution</u> is used to solve this question.
Hypergeometric distribution:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- There are 4 batteries, thus .
- Sample of 2 batteries, thus
- 2 are good, thus .
The probability that <u>both are good</u> is P(X = 2), thus:
0.1667 = 16.67% probability that he selects the two good batteries.
