Question

2 4. You are at a charity event, and you have just purchased 1 ticket for a raffle. Prior to the raffle, you are told that there are 200 people at the event (including yourself), and about of the people at the event purchased tickets to the raffle. Of those people, you approximate that people were equally likely to purchase 1, 2, or 3 tickets. Based on these estimations, what is the probability that you win the raffle? 5. In WWII, enemies would engage in plane-to-plane aerial combat. Unsurprisingly, many planes were lost to crashes; if a bullet strikes a plane in a sensitive area, it's very hard to make it back to base. For the planes that did come back, the mechanics kept track of the location of bullet holes in the fuselage, so that they could reinforce the planes in the most vulnerable locations. 0.6 0.5 0.4 0.3 0.2 0.1 0.0 For American planes, the bullet holes on returning planes were distributed as follows Where should the mechanics reinforce planes so that more of them come back safely? Why? Engine Tail Wing Cockpit Location of bulet hole

Explanation / Answer

5 )

Based on the frequency distribution of the graph , it is evident that most of the planes who came back from the war were hit hard at "wings" , contributing to about 60% of the total distribution. Hence it makes all sense that mechanics reinforces the planes at the wings which are hit the hardest .
