Citing internal NASA studies, the 2002 report for the American Institute of Aeronautics and Astronautics said the risk of a shuttle encountering sprites, elves or blue jets when flying over a thunderstorm is 1 in 100 or less.

And there have been, I think, 113 shuttle flights to date?

Yes, 113.

5 different shuttles have flown and we have lost 2 of those. 6 were built, 1 was used as a trainer and never flew.
