Draw a decision tree and solve it for the following situation. An organization needs to renew its lease of its office space for another year. It can either renew its current lease of the 2 nd floor of an office building or expand the lease to include additional office space on the 3rd floor of the same office building at a cost of $135,000 for the coming year. If it chooses to renew the current lease without expansion, the leasing cost would be $70,000, and the space on the 3rd floor of the same building would be leased to someone else. There is a 75% chance that the additional space would be needed in the coming year. However, if it turns out later that extra space is indeed needed, the organization would have to rent the needed extra space from another office building, which would cost $80,000
