I've worked out the first part of the question, just need help with the second part which is:

The spinner has three sections. While no two are the same size, one of the sections is half the size of another.

•

You are more likely to get 2/3 than one if you sum two spins, but 5/6 is the most likely sum of all.

•

The sum of the three numbers on the spinner is one.

•

The largest number you can get in two spins of this spinner is one.

•

If you spin the spinner twice and add, you get a sum of one about a quarter of the time.

•

If you spun the spinner a hundred times and added up all the numbers, you'd probably get somewhere near 40.

•

DRAW THE SPINNER.

I dont think the spinner is possible given the requirements you provided.

The largest number in two spins is 1 so, one section must have a value of 1/2 (or 6/12)

The most likely value for two spins is 5/6 so, the largest area must have a value of 5/12.

Which means the value for the last area must be 1/12 -- which means there is no way to get a value of 2/3 on two spins.

I would like to see the correct answer.
