Transcribed Image Text:12.
A survey of publishing jobs indicates that 92 percent are completed on time. Assume that three jobs
are selected for study.
a. What is the probability they are all completed on time?
PLAI threes = R) PZS P(S)
a.
b. What is the probability that at least one was not completed on time?
b.
Expert Solution
Step 1
Let , X be the number of jobs completed on time
Here , X→B(n=3 , p=0.92)
The probability mass function of X is ,
; x=0,1,2,.......,n and q=1-p
= 0 ; otherwise
Our aim is to find the following :
a) The probability they are all completed on time
b) The probability that at least one was not completed on time
