This is a binomial experiment and you'll use the binomial probability distribution because:
- There are two choices for each birth. Either you get a girl or you get a boy. So there are two outcomes to each trial. This is where the "bi" comes from in "binomial" (bi means 2).
- Each birth is independent of any other birth. The probability of getting a girl is the same for each trial. In this case, the probability is p = 1/2 = 0.5 = 50%
- There are fixed number of trials. In this case, there are 5 births so n = 5 is the number of trials.
Since all of those conditions above are met, this means we have a binomial experiment.
Some textbooks may split up item #2 into two parts, but I chose to place them together since they are similar ideas.
Answer:
The probability that an applicant does not get a job if he or she has an interview is 20%.
Step-by-step explanation:
- If the applicant has been interviewed, then she/he belongs to the group of 20 people that had an interview.
- 16 of the 20 people who were interviewed were offered a job, which means that 4 of the 20 people interviewed were not offered a job.
- Then, 4/20= 20% of the people who were intervied did not get a job, which means that the <u>probability that an applicant does not get a job if he/she were interviewed is 20%</u>.
- Pat attention: this probability results from analysing the probability of getting a job once you have had an interview (this condition restricts our attention to the group of 20 people who had an interview, and not to the hole group of 500 people who did apply for the job).
Answer:
the answer is 8.5
Step-by-step explanation:
divide 85 by 10 to get 8.5 for all the dimension
Answer:
45,000
Step-by-step explanation:
You should divide 20 by 600 to see how many miles he would run per mile
and you take 30 x 1,500 to get your answer
