Points VIOUS ANSWERS BBBASICSTAT6 6.R.015.5. Hawaii shark attacks are very rare. Furthermore, about 55% of all shark attacks are serious, but not fatal. You are scheduled to give a talk at a local scuba club in Honolulu and want to include a hef statistical profile regarding the most recent six shark attacks, all of which were nonfatal. Letr be the number of nonfatal attacks out of a random sample of six shark attacks.
