$0.00027$ and $0.9996$

California (7209) or Texas (6181) numbers add up to 13390, the probability is $p=13390/49904000=0.00027$ Not from one of these four listed states: total number of these four states 20130, the probability for these four states is $20130/49904000=0.0004$, so the probability of not from these four states is $1-0.0004=0.9996$
