The probability of getting the first answer correct is 1/2
The probability of getting the first two correct is 1/2 * 1/2 = 1/(22)
The probability of getting all 9 correct is 1/(29) = 1/512 which is just under 0.2%
10/12
The probability is 0.56
Empirical
It depends on what the random variable is, what its domain is, what its probability distribution function is. The probability that a randomly selected random variable has a value between 40 and 60 is probably quite close to zero.
3/10 or 0.3

1/3. Indeed, there were four answers you had to choose from. If one is eliminated as you know it is definitely wrong, then you are left with three possible answers, one of which is correct. Thus you have 1 correct answer out of three possible, and the probability to randomly pick the correct one is 1 out of 3, or 1/3 or 33.333 %
If you answer randomly, 1 in 8.
Depends on the questions, and how they are answered. T/F, multiple choice, matching, essay, etc. Could be randomly answering, making educated guesses, or applying some amount of knowledge on the subject. Each of these impacts the probability of supplying correct answers.
It is 0.0547

Non probability sampling is where the samples are not selected randomly.
As all the angles in a square measure 90°, the probability of 2 randomly chosen angles being congruent is 1.
Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
