A group is planning to back the production of a new musical at lusaka playhouse. it would cost k100 000 to stage for the first month. if well received by critics, it will be kept on for a further six months earning a profit of k350 000. if critics dislike it, it will close at the end of the first month. there is a 50: 50 chance of a favourable review. should the group invest in the musical?
