no equal answer
a and b both have the probability of 3/4
The answer depends on what population characteristic A measures: whether it is mean, variance, standard deviation, proportion etc. It also depends on the sampling distribution of A.
The probability is 0.664
Impossible
The answer depends on what the distribution is!

a and b both have the probability of 3/4
The probability that an event will occur plus the probability that it will not occur equals 1.

It does not matter.
The probability is 0.664
Yes the proportion for them both is 1:3
1000:1
Probability equals favorable outcomes divided by total number of outcomes.
