Two died last year in Yellowstone. The first startled a sow with cubs. The second may have been the same sow and some say it was predation. Neither had bear spray with them.
One died the year before just outside the park. I believe it was a startled grizzly as well.

3.6 million visitors in 2010, I think your odds are very low.
