The answer is no. this is because if you toss a coin two times the probability of landing on heads twice is 1/4. if it doesn't land on tails twice it can land on heads once and tails once. this means there are more possibility and cannot be the same
R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32
Subtract first equation from second equation.
2R=32 so R=16
Plug into first equation
16=2K so K=8
Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works
So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
The process and the answer is shown in the following picture. The five ones are all the same.
