What is the probability of rolling a 2 on the first dice and an odd number on the second dice?
None, because you cannot have the first or second dice: it is the first die or second die. The probability is 1/6 * 1/2 = 1/12
How to solve probability questions?
Count the total number of ways it can turn out. Count the number of ways that are the condition you're looking for. The probability of the outcome you're looking for is is the second number divided by the first number.

What is theoretical probability of picking 2 squared numbers out of 15?
The answer depends on whether the first number is replaced before picking the second. If not, the probability is 0.029

What is the theoretical probability that tossing 3 coins will all match?
The probability that the second coin matches the first is 0.5 .The probability that the third coin matches the first is 0.5 .The probability that the second and third coins both match the first is (0.5 x 0.5) = 0.25 = 25%
Two dice are thrown. What is the probability of getting the same number?
The first dice can show any number. However the second dice has a 1 in 6 chance of being the same as the first. Hence the probability of getting two numbers the same is 1/6.
What is the probability when you roll two dice that you roll an odd number on the first die and a 1 on the second die?
The probability when you roll two dice that you roll an odd number on the first die and a 1 on the second die is 1 in 12. The two die are sequentially unrelated, so you can consider them separately. The probability of rolling an odd number is 3 in 6, or 1 in 2. The probability of rolling a 1 is 1 in 6. Multiply the two probabilities together and you get 3 in 36, or 1 in 12.
What is the first number in a probability ratio?
The number of "favourable" outcomes.
