You need a null hypothesis first. You then calculate the probability of the observation under the conditions specified by the null hypothesis.

It depends on the global, or population, resistance to ciprofloxin.

There are 26 letters and 5 vowels so 5/26.

over 97564 billion outcomes

There are 40,320 ways to arrange eight letters. In this case, around sixty of those ways will result in English words.

Yes SD is ofcourse measure of precision

There are 40,320 ways to arrange eight letters. In this case, around sixty of those ways will result in English words.

The answer depends on whether the confidence interval is one sided or two sided.

It is approx 78.8%

No. There are 24 hours in a day, not 12!

Not necessarily. There may not even be a way to work out a theoretical probability. Furthermore, there is always a chance, however small, that the experimental probability is way off.

Its probability. The probability for a certainty is 1.

Given two events, A and B, the conditional probability rule states that

P(A and B) = P(A given that B has occurred)*P(B)

If A and B are independent, then the occurrence (or not) of B makes no difference to the probability of A happening. So that

P(A given that B has occurred) = P(A)

and therefore, you get

P(A and B) = P(A)*P(B)

3/4

It is a number in the interval [0, 1].
