The numbers on electronic displays ... like on alarm clocks or digital watches ... are made out of what's called "7-segment" displays.
For each digit, there's a set of 7 tiny LED's that are laid out something like this: _ /_/ /_/
Then, all of the digits from 0 to 9 can be made just by lighting up some of the segments, and keeping the rest turned off.
This question is asking for a table that shows how many segments are lit up to make each digit ... not which ones, but just how many. This is something the design engineers want to know, so that they can be sure to provide enough power inside the clock to light up all the digits.
Look at the picture I attached. It shows all the digits, 0 to 9, the way they look in 7-segment displays, and on the right side, the number of segments that are lit up to make each digit.
I think this is something like what the question is asking for.
