Daniaal Sanchez 2021-09-22Two firms V and W consider bidding on a road-building job, which may or
may not be awarded depending on the amounts of the bids. Firm V submits a
bid and the probability is 0.8 that it will get the job provided firm W does not
bid. The probability is 0.7 that W will be bid, and if it does, the probability that
V will get the job is only 0.4
If V gets the job, what is the probability that W did not bid?
