The translation of Ac into words.

Answer to Problem 1CR

Solution: The individual does not own a cell phone.

Explanation of Solution

Given: A = the event that an individual owns a cell phone.

The complement of an event A is denoted as Ac.

According to the provided information for an individual, the event A is defined as ‘owns a cellphone’. So, the complement of event A is ‘the individual does not own a cellphone’.

Answer to Problem 1CR

Solution: The event that an individual owns a cell phone and a laptop computer.

Explanation of Solution

Given: A = an individual owns a cell phone, B = an individual owns a laptop computer.

Both the events A and B, occurring together is denoted as (A and B).

According to the provided information for an individual, the event A is defined as ‘owns a cellphone’ and the event B is defined as ‘owns a laptop computer’. So, both the events A and B occurring together can be defined as ‘the individual owns a cellphone and a laptop computer’.

(c)

To determine

The translation of A or B into words.

Answer to Problem 1CR

Solution: The individual owns either a cell phone or a laptop computer or both.

Explanation of Solution

Given: A = an individual owns a cell phone, B = an individual owns a laptop computer.

The occurrence of either event A or B or both is denoted as (A or B).

According to the provided information for an individual, the event A is defined as ‘owns a cellphone’ and the event B is defined as ‘owns a laptop computer’. So, the occurrence of either event can be defined as ‘the individual owns a cellphone or a laptop computer or both’.

(d)

To determine

The translation of A|B into words.

Answer to Problem 1CR

Solution: The individual is a laptop computer owner who owns a cellphone.

Explanation of Solution

Given: A = an individual owns a cell phone, B = an individual owns a laptop computer.

The occurrence of event A given that event B has occurred is denoted as (A|B).

According to the provided information for an individual, the event A is defined as ‘owns a cellphone’ and the event B is defined as ‘owns a laptop computer’. So, the occurrence of A given that event B has occurred is defined as ‘the individual who is an owner of a laptop computer, owns a cellphone’.

(e)

To determine

The translation of B|A into words.

Answer to Problem 1CR

Solution: The individual is a cellphone owner who owns a laptop computer.

Explanation of Solution

Given: A = an individual owns a cell phone, B = an individual owns a laptop computer.

The occurrence of event B given that the event A has occurred is denoted as (B|A).

According to the provided information for an individual, the event A is defined as ‘owns a cellphone’ and the event B is defined as ‘owns a laptop computer’. So, the occurrence of event B given that event A has occurred can be defined as ‘the individual who is an owner of a cellphone, owns a laptop computer’.

In order to find probability, you can use this formula in Microsoft Excel: The best way to understand and solve these problems is by first drawing a bell curve and marking key points such as x, the mean, and the areas of interest. Once marked on the bell curve, figure out what calculations are needed to find the area of interest. =NORM.DIST(x, Mean, Standard Dev., TRUE). When the question mentions “greater than” you may have to subtract your answer from 1. When the question mentions “between (two values)”, you need to do separate calculation for both values and then subtract their results to get the answer. 1.  Compute the probability of a value between 44.0 and 55.0. (The question requires finding probability value between 44 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 44, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the…

What is the probability of more than 1.50 inches of rain for the month? The best way to solve this problem is begin by creating a chart. Clearly mark the range, identifying the lower and upper…
Problem 1: The mean hourly pay of an American Airlines flight attendant is normally distributed with a mean of 40 per hour and a standard deviation of 3.00 per hour. What is the probability that the hourly pay of a randomly selected flight attendant is: Between the mean and $45 per hour? More than $45 per hour? Less than $32 per hour?   Problem 2: The mean of a normal probability distribution is 400 pounds. The standard deviation is 10 pounds. What is the area between 415 pounds and the mean of 400 pounds? What is the area between the mean and 395 pounds? What is the probability of randomly selecting a value less than 395 pounds?   Problem 3: In New York State, the mean salary for high school teachers in 2022 was 81,410 with a standard deviation of 9,500. Only Alaska’s mean salary was higher. Assume New York’s state salaries follow a normal distribution. What percent of New York State high school teachers earn between 70,000 and 75,000?
