What is the definitions of a theoretical probability?
To me, the theoretical probability is what is termed the classical probability. This says the probability is the number of ways an event can occur divided by the number of possible events. Forexample, flip a coin. The theoretical probability for heads is 1/2. However, flip a coin 10 times and you will probably not get 5/10 (or 1/2). Doing the actual experiment to determine the probability is called relative frequency approximation.
Example of joint probability?
Joint probability is the probability that two or more specific outcomes will occur in an event. An example of joint probability would be rolling a 2 and a 5 using two different dice.
Determine the probability of the sum of 8 in the single tossed in a pair of fair dice?
The probability of rolling a sum of 8 is approx a 14% chance. There are 36 possibilities when rolling 2 die. There are 5 possibilities of rolling a sum of 8. → Probability = 5/36 = 5/36 x 100% ≈ 14%.
How did theoretical probability get its name?
The theoretical probability of an event is the probability that is calculated on theoretical considerations. This normally entails modelling the experiment and then employing the laws of science to determine the event space and the probabilities of the outcomes. For example, suppose you wish to determine the theoretical probability of getting the number 5 when you roll a normal die. There are 6 possible outcomes. If the die is fair then each of these outcomes is equally likely. Therefore the probability of any particular number - for example, 5 - is 1/6.
When rolling a pair of dice determine the probability of rolling a number less than 7?
5 over 11

What is the probability of rolling a 5 when using 2 number cubes?
It is 4/36 or 1/9.
Using a six-sided die what is the probability of rolling either 5 or a 6?
1/3
What is the probability that 20 substandard welds will be found out of 300 randomly selected samples knowing that 5 percent will be substandard?
Using the Poisson approximation, the probability is 0.0418
If you roll two dice what is the probability of the event that you roll a total of five on the two dice?
uummm!!!! The probability would maybe close to 5 or 4. * * * * * The answer is clearly incorrect because the probability of an event cannot be greater than 1. The actual probability, assuming the dice are fair, is 4/36 = 1/9 = 11.11...%
What is the Probability of 5 out of 8 62?
5 out of 8 is 62.5%
The probability of rolling 5 40 times is 12 What is the probability of rolling 5 500 times?
Probability is a number between 0 and 1. The probability of an event cannot be 12.
How do you determent the probability?
To determine a probability:Take the number of outcomes that you wantDivide it by the number of total possible outcomesFor example, to determine the probability of taking a green ball out of a bag with 5 red balls, 5 blue balls and 5 green balls:Take the number of outcomes that you want: 5Divide it by the number of total possible outcomes: 15 divided by 5 = 1/3Write the answer as a fraction (eg. 1/3), a decimal (eg. 0.33) or a percentage (eg.33%).
