The possibility of rolling a #3# on a fair die and getting tails on a coil is #1/12#. Based on this probability, there are #12# possible outcomes. As only 1 out of 12 possiblities would get this outcome, it is not a likely outcome. Show
The probability of rolling a #3# on a fair die is #1/6# because there is only one #3# out
of #6# numbers. The probability of getting tails on a coin is #1/2# because there are #2# possibilities and tails is one of them. To get the probability of rolling a #3# on a fair die and getting tails on a coil, we multiply their probabilities: A branch of mathematics that deals with the happening of a random event is termed probability. It is used in Maths to predict how likely events are to happen. The probability of any event can only be between 0 and 1 and it can also be written in the form of a percentage.
If we are not sure about the outcome of an event, we take help of the probabilities of certain outcomes—how likely they occur. For a proper understanding of probability we take an example as tossing a coin: There will be two possible outcomes—heads or tails. The probability of getting heads is half. You might already know that the probability is half/half or 50% as the event is an equally likely event and is complementary so the possibility of getting heads or tails is 50%. Formula of Probability
Some Terms of Probability Theory
Some Probability FormulasAddition rule: Union of two events, say A and B, then
Complementary rule: If there are two possible events of an experiment so the probability of one event will be the Complement of another event. For example – if A and B are two possible events, then
Conditional rule: When the probability of an event is given and the second is required for which first is given, then
Multiplication rule: Intersection of two other events i.e. events A and B need to occur simultaneously. Then

What is the probability of rolling a 3 on a 6 sided dice?To understanding probability we take an example as rolling a dice: There are six possible outcomes—1, 2, 3, 4, 5, and 6. The probability of getting any of the numbers is 1/6. As the event is an equally likely event so the possibility of getting any number is the same in this case it is 1/6 or 50/3%.
What is the probability you get a 3 or a tail?1 Answer. The possibility of rolling a 3 on a fair die and getting tails on a coil is 112 . Based on this probability, there are 12 possible outcomes. As only 1 out of 12 possiblities would get this outcome, it is not a likely outcome.
What is probability of getting tail side on a coin and a 6 on a dice?The ratio of the number of favorable outcomes to the total number of outcomes is called probability. The probability of an event always lies between 0 to 1. Given that both the events occured simultaneously. Thus, the probability of getting a tail and a six when a coin is tossed and a cube is rolled is 1/12.
What is the probability of getting a 3 after tossing the rolling die?∴ Probability of getting 3=61.
