Step by step solution

01

Content Introduction

A set of outcomes of a random experiment can be defined as an event in probability. All possible outcomes of an experiment are represented by the sample space. In probability, there are various different sorts of events.

02

Content Explanation

The completed table is as follow:

the probability that person smoked cigarettes per day is

P(personsmokedcigarettes11to20perday)=35065100450P(personsmokedcigarettes11to20perday)=0.35

A box has two balls, one white and one red. We select one ball, put it back in the box, and select a second ball (sampling with replacement). Find the probability of the following events:

a. Let F = the event of getting the white ball twice.

b. Let G = the event of getting two balls of different colors.

c. Let H = the event of getting white on the first pick.

d. Are F and G mutually exclusive?

e. Are G and H mutually exclusive?

The probability that a man develops some form of cancer in his lifetime is 0.4567. The probability that a man has at least one false positive test result (meaning the test comes back for cancer when the man does not have it) is 0.51 Let: C = a man develops cancer in his lifetime; P = man has at least one false positive. Construct a tree diagram of the situation.

U and V are mutually exclusive events. P(U) = 0.26; P(V) = 0.37. Find:

a. P(U AND V)

b. P(U|V)

c. P(U OR V)

Use the following information to answer the next six exercises. There are 23countries in North America, 12countries in

South America, 47countries in Europe, 44countries in Asia, 54countries in Africa, and 14in Oceania (Pacific Ocean

region).

Let A = the event that a country is in Asia.

Let E = the event that a country is in Europe.

Let F = the event that a country is in Africa.

Let N = the event that a country is in North America.

Let O = the event that a country is in Oceania.

Let S = the event that a country is in South America.

Find P(O).

United Blood Services is a blood bank that serves more than 500hospitals in 18 states. According to their website, a person with type O blood and a negative Rh factor (Rh-) can donate blood to any person with any blood type. Their data show that 43% of people have type O blood and 15% of people haveRh- factor; 52%of people have type O or Rh- factor.

a. Find the probability that a person has both typeO blood and the Rh- factor.

b. Find the probability that a person does NOT have both type O blood and the Rh- factor
