As you examine the bridges more closely, you'll notice that each one has a sign with some numbers. You assumed these are the number of people who have safely crossed each bridge. So you want to calculate the average and pick the bridge with the highest number. Again, you want to be wise about it and you will find an average without minimum and maximum value. Very often, it is useful to split a problem into smaller problems and solve them one by one. Question $4\mathrm{.}1$: Write a function that takes a non$-$empty list of a number of people who crossed a bridge and calculates the average for the given list according to our definition of the average above. Round the number to the second decimal place and return your answer. If the length of the list is less than or equal to two, then return $0\mathrm{.}0$ Hints: min$(),$ max$()$ might be useful sum$()$ might be useful Use round$()$ built$-$in function.
