Answer:
Step-by-step explanation:
Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.
Given that (a,b) R (c,d) if
Or (a,b) R (c,d) if determinant
a) Reflexive:
We have (a,b) R (a,b) because ab-ab =0 Hence reflexive
b) Symmetric
(a,b) R (c,d) gives ad-bc =0
Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
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.
