Question

A technician services mailing machines at companies in the Phoenix area. Depending on the type of malfunction, the service call can take 1, 2, 3, or 4 hours. The different types of malfunctions occur at the same frequency. (a) Develop a probability distribution for the duration of a service call. x f(x) 1 2 3 4

Answer 1

Answer:

$p(1)=p(2)=p(3)=p(4)=0.25$

Step-by-step explanation:

-The total number of outcomes is 4.

-Given that the outcomes occur with the same frequency.

-Therefore they all occur with the same frequency, 1/4=0.25

$p(1)=p(2)=p(3)=p(4)=0.25$

-The probability distribution for the duration of a service call is attached.
