How did I get here

I don’t really know. But I do know that you can find the probability of 3 or fewer breakdowns for the robot line by multiplying them sequentially. No idea about the hours thing, seems very confusing to me.

The Plot(s)

Mah plot:

Big text. But what does it mean?

I’m glad you asked. I don’t know. But here is a graph:

curve(dnorm(x,200,30),120,280,main="Bagging PDF", ylab="f(x)", xlab="x")

This plot goes from 120 to 280!

Just like in the problem! WOW!!

It also has the deviation as 30!!!11!!

Just HOW do you find the probability that the package is sealed with less that 150g??

I don’t know and don’t have the time to find out. Have a good day.
