Solution 10E
Step1 of 4:
Let us consider a events:
I = personal illness
F = family issues
N = personal needs
E = entitlement mentality
S = stress.
Also we have 34% of unscheduled work absence due to ‘personal illness’, 22% for ‘family issues’, 18% for ‘personal needs’, 13% for entitlement mentality’, and 13% due to stress.
Here our goal is:
a). We need to list the sample points for this experiment.
b. We need to Assign reasonable probabilities to the sample points.
c). We need to the probability that the absence is due to something other than personal illness.
Step2 of 4:
a).
From the given information we have 5 sample points and they are:
{I, F, N, E, S}
Step3 of 4:
b).
