1. To calculate this answer we multiply for Chris.
2. The LOVE and DEAL probability is .8 .1 just as before and
3. multiply in the prior of .5.
4. And product of the .1 times .8 times .5 is 0.04.
5. The math changes for SARA.
6. She was as would LOVE with .5 probability.
7. DEAL with .2, and again our prior is 0.5.
8. This is 0.05.
9. Now, to normalize them to bring them into a form where they add up to 1,
10. we realize that the sum right now is 0.09.
11. So we have to divide 0.04 by 0.09 and that gives us 0.444.
12. An approximation.
13. And the 5 gives us 0.555.
14. If we add them up you might get 0.99999 or 1.
