The probability is close to 0. You would need to know details of all the companies in the world that filed reports. Chances of finding one whose profits were exactly 63% are pretty slim!
No. Probability is always represented as a positive ratio/fraction/percent.

Using the Poisson approximation, the probability is 0.0418
It is 0.73 = 0.343

The probability that both will be hopelessly romantic is .0081 .009^2 = .0081
This is a binomial probability distribution; n=12, r=2 & P=.05. Read directly from the table probability of 2 is .099 (plugging this data into my calculator gives 0.09879).
The probability of 33.3 percent is 0.333.
probability of 75 percent = 3/4
