The decision has come down whether to expand now with a large facility or to undertake small expansion. Management has estimated the following: - The demand when being high is 0.60 - The demand when being Low is 0.40 Profits for cach alternative have been estimated: Large expansion has an estimated profitability of either $1000 000 or $600 000, depending on whether demand turns out to be high or low. Small expansion has a profitability of $500 000 assuming that demand is low. Small expansion with an occurrence of high demand would require considering whether to expand further. If the company expands at that point, the profitability is expected to be $700 000. If it does not expand further, the profitability is expected to be S500 000 Required: 2 Draw a decision tree diagram and add the information that you are given(marks) b.
