Answer:
24
Step-by-step explanation:
Just multiply the choices together.
1 *4 *3 * 2 = 24. The number is small enough that you could almost list all the choices.
Answer:
Odds are 5
Step-by-step explanation:
45% turns into 45/100, which is 0.45% of people in the country. If one person is selected, I would think,, oh! 45 is less than 50, which is the middle of all the people in that county. That would mean the person selected is not having high blood pressure. The odds are 5.
Third side must be greater than (12 -7) or 5 and less than (12 + 7) or 19
So, third side could be A C E or F
Using the hypergeometric distribution, it is found that there is a 0.0455 = 4.55% probability that both light bulbs failed the test.
The bulbs are chosen without replacement, and this is why the <u>hypergeometric distribution</u> is used to find the probability.
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:
- 12 bulbs, thus
- 3 failed the test, thus .
- 2 are selected, thus .
The probability that <u>both failed the test</u> is P(X = 2), thus:
0.0455 = 4.55% probability that both light bulbs failed the test.
