Anything to the power of 1/3 means to find the cube root. We can simplify this to:
I just multiplied 4 and 1/3 (because of the second index law

a = 10/3
Hope this helps!
The greatest common factor is 48
I think it is 9 6/9 but im not quite sure .
The key word here is "or". If it's an OR question, you add the probabilities together. If it says "and", you multiply them together
As it is an OR question though, you add them.
So:
15 + 5 = 20%
