when jarrod heads out to the bike park, he finds that 80% of the time he attemps a 360. if he attemps a 360, then he has an 90% chance of landing it. if he does not land it, he ends up injured. on average, how many days during the first week of the school hoidays (7 days long) can jarrod expect to injure himself from bike ridie?

He will attempt a 360.... 7 (.80)  = 5.6 days


And 10%  of these days he will injure himself = (.10) * 5.6  = .56 days
