For each of the following decisions,which alternative would you choose?
1)In the final seconds of a game against a traditional rival,the coach of a university football team may choose a play that has a 95 per cent chance of producing a tied score,or one with a 30 per cent chance of victory,but certain defeat if it fails.
2)The president of a major New Zealand company must decide whether to build a new plant within New Zealand that has a 90 per cent chance of producing a modest return on investment,or to build it in a foreign country with an unstable political history.The latter alternative has a 40 per cent chance of failing,but the returns would be enormous if it succeeded.
3)A university student with considerable acting talent must choose a career.She has the opportunity to go on to medical school and become a physician,a career in which she is 80 per cent likely to succeed.She would rather be an actress,but realises that the opportunity is only 20 per cent.
