Spring 2019 LTAM solution -- some errors were fixed

I want to thank Dr. Abraham Weishaus for pointing out some errors in the solution.

These errors were fixed.

Page 1 "Version history" section of the new PDF explains what parts were fixed.

MC q1 correction

I just realized that for MC q1 the selection factors are 0.75, not 0.80.

Joy, the first contributor, used 0.75 when she sent me her solutions, but somehow I changed 0.75 to 0.8 by mistake when I was creating the PDF using LaTex.

The correct answer is 12p[68]=0.81972277, which still points to C, due to my good luck.

WA 3c was updated using the age-last-birthday based premium

WA 3c was updated. The ALB based premium is slightly lower than the exact age based premium.

By now, I think all the errors were fixed.

Q17

Q17 is calculated with discrete d in the solution when it should be delta.

You are right. I should have used the force of interest delta, not d. Thanks.
