Explanation / Answer

The last option is met with all the following condition.

In the last figure, we clearly see that X lies in the interval [0,10].

for a given week, there is an 80% chance that he will make 3 to 5 blunders. that is (0.2+0.44+0.16)=0.8 means 80% chance.

and never a week goes by that he doesn't make at least one blunder. that is, in 1 to 10 week there is at least one blunder, we see it clearly in the last figure.

in last figure, he has made 10 blunders in one week.
