Convert all statistics into percentages:
CA: 3/25=0.12 -> 12%
NY: 3/50=0.06 -> 6%
TX: 2/25=0.08->8%
(A) Out of the three states, California has the largest population
(B) Out of the three states, NY has the smallest population
(C) USA=100%, CA+NY+TX=26%, therefore 74% of USA do not live on those three states.
