probability of 1st to die

[rblum50]

I was recently asked by an attorney to calculate probability of a person aged 57 dying before another person age 70. Pulling out my old (very old) copy of Life Contingencies by Jordon, I found the formula for the "q" that I needed.It looks like this:

1

(infinity sign) q

57:70

I don't have any software to calculate this value directly. I can develop it from scratch using an Excel spreadsheet, but, that would take me hours. Any suggestions?

Thanks for any suggestions,

Rick
