Answer:
Follows are the solution to this question:
Step-by-step explanation:
In point (1):
Now that it is possible to obtain the joint distribution as:
In point (2):
Likely that now It (the IT column total throughout the table above) seems to be the random individual selected = 0.4285;
Here, 0.4285 is the necessary probability.
In point (3):
The way of its worker's sleep at work =0.5871 ( first row total in the above table )
Here 0.5871 was its required probability.
In point (4):
In this as employee slept at work, he is likely to also be from IT to be calculated with:
In point (5):
In an individual is also an official government, its chance of getting sleep at work is measured when:
In point (6):
Therefore, 2 cases aren't independent, because P(IT) P(Yes) is not the same as P(IT and Yes), which also implies that P(IT|Yes) is not the same as P (IT), therefore "" is correct.
