According to a survey published by compsych corporation, 54% of all workers read e-mail while they are talking on the phone. suppose that 20% of those who read e-mail while they are talking on the phone write personal "to-do" lists during meetings. assuming that these figures are true for all workers, if a worker is randomly selected, determine the following probabilities:

a. the worker does not write personal "to-do" lists given that he reads e-mail while talking on the phone.
b. the worker does not write personal "to-do" lists given that he reads e-mail while talking on the phone.
c. the worker does not write personal "to-do" lists and does read e-mail while talking on the phone.

The probability of the worker does not write personal "to-do" lists given that he reads e-mail while talking on the phone is P=0.8.

Step-by-step explanation:

a) The worker does not write personal "to-do" lists () given that he reads e-mail while talking on the phone ():

If it is given that he reads e-mail, we pick out of the 54% of the workers. In this group of workers, 20% write to-do list, so it means that 80% doesn't write to-do lists.

answer is 144

step-by-step explanation:

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
