Please help me with this homework

The Computex firm submitted separate bids to the Ministry of Education for the supply of office furniture and microcomputer devices. The experience of this company in the field of tenders allows us to estimate its chances of obtaining the office supplies contract at 60%. If this contract is awarded to it, the firm evaluates its chances at 2 to 1 for obtaining the microcomputer contract. However, if the office automation contract escapes her, she still estimates that she has a 30 out of 100 chance of being awarded the microcomputer contract. Let us define the various events associated with this situation as follows: E: the office furniture contract is deployed to Computex. E2: the microcomputer contract is delegated to Computex. a) Prepare the tree diagram indicating the possible events and the corresponding probabilities. b) Specify in words what the following events represent: i) E E ii) E E2 iii) EE2. c) What is the probability that Computex will obtain both contracts? d) What is the probability that Computex only gets the microcomputer contract? e) What is the probability of obtaining the microcomputer contract whether or not Computex obtained the office automation supplies contract? f) Computex has just announced that it has won the microcomputer contract. What is the probability that she got office furniture
