For questions 1 through 3 use the table below. The table shows the number of smokers and nonsmokers by gender among 220 people. Assume one person is chosen at random from the 220.

1. If a smoker is chosen at random, the probability that the person is male is?

2. If a male is chosen at random, the probability that he is a smoker is

3. If one person is chosen at random from the 220 in the table above, the events of "Smoker" and "Male" are (i.e. independent , dependent or mutually event)

Researchers have determined that patients who are smokers have 18% chance of contracting a serious illness, whereas only .06 probability that a non smoker will contract a serious illness.
23% are all smokers
77% non smokers
What is the probability that a given patient if the patient has a serious illness?

According to recent research, 80% of adult smokers started smoking before they were 18 years old. Suppose ten smokers are randomly selected and the number of smokers who started smoking before 18 is recorded.
A) Find the probability that exactly eight started smoking before turning 18 years of age.
B) Find the probabili

Patients
23% (smokers) -18% have a chance of contracting a serious illness
77% (non smoker) - 6% have a chance of contracting a serious illness
I'm trying to figure out the probability that a given patient is a smoker if the patient has a ser

The centers for disease control say that about 30% of high school students smoke tobacco (down from a high of 38% in 1997). Suppose you randomly select high-school students to survey team on their attitudes toward scenes of smoking in the movies. what's the probability that
A) none of the first 4 students you interview is a

A large research hospital has accumulated statistical data on its patients for an extended period of time. Researchers have determined that patients who are smokers have an 18% chance of contracting a serious illness such as heart disease, cancer, or emphysema, whereas there is only a .06 probability that a non smoker will cont

Cotinine Levels of Smokers When people smoke, the nicotine they absorb is converted to cotinine, which can be measured. A sample of 40 smokers has a mean cotinine level of 172.5. Assume that the population standard deviation is known to be 119.5, find a 90% confidence interval estimate of the mean cotinine level of all smoker

An ectopic pregnancy is twice as likely to develop when the pregnant woman is a smoker as it is when she is a nonsmoker. If 32 percent of women of childbearing age are smokers. What percentage of women having ectopic pregnancies are smokers?

The problem is many smokers are less productive than non-smokers.
The purpose of a research project on this topic is to determine if a specific solution strategy improves productivity of smokers.
Therefore, what would be some recommendations for future researchers and what type of solicitation of audience feedback is there
