The proportion of people who move 2 or more deciles between period *A* and period *B* in Population 2 is 75%. The size of Population 2 is 6,073.

To give a sense of the different magnitude of change in the two populations I would like to say that "the probability of moving two or more deciles in Population 1 was *X*, whereas in Population 2 it was *Y*".

Can anybody help me to find a way to express the probability of moving 2 or more deciles in each population?

Thanks
