Answer: Our required probability is 0.55.
Step-by-step explanation:
Since we have given that
Probability that chance of winning the hotel bid = 40%
Probability that no chance of winning the hotel bid = 100-40=60%
Probability that chance of winning the office building bid = 25%
Probability that no chance of winning the office building bid = 100-25 = 75%
So, Probability that the company will win at least one contract is given by
Hence, our required probability is 0.55.
