Ineed . and could you explain to me as well

It is the third one out of all 4

Second choice

Step-by-step explanation:

Since a = b and b = c, then b = c is exactly what that axioms states. a is equal to b, which is equal to c, so b must be equal to c.

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.
