- Use the bar graph below, which shows the highest level of education received by employees of a company, to find the probability that the highest level of education for an employee a Random is B.
__Must insert Data
The probability that the highest level of education for an employee chosen at random is B is?
- Determine whether the Events E & F are Dependent
Justify your answer.
- E: A person having a high GPA
F: A person being highly organized
Chose the correct one:
- E & F: are dependent because having a high GPA has no effect on the probability of a person being highly organized.
- E & f: are independent because highly organized has no effec on the probability of a person having a high GPA
- E: A randomly select having a GPA
F: A notre randomly seleced person having a low GPA.
- In the general population, 1 women in 10 will developpe breast cancer. Research has shown that 1 woman in 550 carriers a mutation of the Breast Cncer gene. Nine out of 10 women with this mutation developed Breast Cancer.
- Find the probability that a randomly select woman will developed Breast Cancer given that she has mutation of BRCA gene.
The probability that randomly selected woman will developed Breast Cancer given that she has a mutation of BRCA gene is ??
- Find the probability that the randomly selected woman will carry the mutation of the BRCA gene will developed BRCA.
The probability that a randomly selected woman will carry he gene mutation and developed cancer is???
- Are the events of carrying this mutation and developing cancer
Independent or dependen/
- The table shows the result of a survey in wich 141 men 144 women workers ages 25 to 64 were asked at least one months income set a side for emergencies. Compleed part A through D
|Less than 1 month income||65||83||148|
|1 month income or more||76||61||137|
- Find the probility that randomly selected whether has one month income or more set aside for amergencies
Probability is????? (round near thousands)
- Given that randomly selected worker is a male, find probability that the worker has less than 1 month’s income.
Probability is ????? (round near thousands )
- Given that randomly selected worker has 1 month income or more, find the probability that worker is a female
- Are the events “having less than 1 month income saved” and “ are independent or dependent”?
- Decide if the events are mutually exclusive
Event A: randomly selecting a nurse
Event B: Randomly selecting a male
A= Yes because someone who is a nurse can be male
B= No because someone woho is a nursse cannot be a male
C= Yes because who is nurse cannot be a male.
D= No because someone who is a nurse can be male
- A standard desk of card contains 52 cards. I card is selected from the desk.
- Compute the probability of randomly select a Diamond or Heart.
- Compute the probability of randomly selecting a Diamond or Heart, Club.
- Compue the probability of randomly selecting a Five or Heart.
- P (Diamond or Heart)=??? (type integer or simplified fraction)
- P (Diamond, Heart, Club)=???? (type integer or simplified)
- P (Five or Heart)= ????? (type integer or simplified)
- Table below shows the result of survey that asked 2871 people whether they are involved in any types of charity work.
A person is selected at random from the sample
|Frequency||Occasionally||not at all||Total|
- Find the probability that the person is frequently or occasionally involved tochasting work.
P(Being frequently involved or being occasionally involved)= ??? nearest thousand
- Find the probability that the person is female or not involved in charity work at all.
P(Being female or not being involved)= ????? nearest thousands
- Find the probability that the person is male or frequency involved in charity work.
P(Being male or being frequently involved)
- Find the probability that the person is female or not frequently involved in charity work.
P(being female or not frequent involved)?????
- Are the event “being female” and “being frequently involved in charity work” mutually exclusive. EXPLAIN:
- Yes because no females are frequently involved in charity work
- Yes because 203 females are frequently involves in charity work.
- No because 203 females are frequently involved in charity work
- No because no females are frequently involves in charity work
- Perfom the indicated calculation
8C4 / 12C4 = ???? round to the nearest thousand
