Answer:
if there are 3 colours and 3 sections then answer is 1/3
if there are 3 colours and 6 sections its still 1/3
if there are 3 colours and an odd number then it becomes 1/7 or 2/7 etc
if there are 2 colours and 4, 6 or 8 sections then if all equal it is 1/2, 1/3. 1/4
if there are 4 colours and equal amounts then it is 1/4
if odd amounts then you need to add up how many grey and how many others ie) 2 grey and 3 others = 2/5 as 5 would be total and represent the denominator in fractions.
Grey is the numerator.
Hope that helps.
First you add then you fractionalise.
Then for your spin 2 you must multiply each fraction.
If both spinners are the same its same fraction x same fraction
If both spinners different then its fraction 1 x fraction for spinner 2.
