You do not need to but it can help to identify all the possible outcomes so that you don't miss any out (by mistake).

What is the probability of choosing an odd number?
If you have an equal amount of odd and even numbers in a determined sample space, the probability of choosing and odd number is 1/2 (.5).
When Rolling a die 5 times and noting whether it is odd or even on each roll what is the size of sample space?
It all depends on what you do with the information that you note. If you count up the number of odds [or evens] in the five rolls, your sample space is {0,1,2,3,4,5} with size 6. If you look for whether you had more odds than evens your sample space is {Y,N}, with size 2. If you subtract the number of even outcomes from the number of odd outcomes, your sample space is {-5,-4,,...,4,5} which is of size 11.
What does it mean if the probability of an even number is 0?
If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.
What is the probability of rolling an even with one roll of a numbers cube. express the probability as a decimal.?
What is the probability of rolling an even with one roll of a numbers cube.
What is the probability that a 2 digit number is even?
The probability is 1/2.
What is the probability of choosing an odd number?
If you have an equal amount of odd and even numbers in a determined sample space, the probability of choosing and odd number is 1/2 (.5).
Which of the following is the best definition of the sample space Space of a probability event?
Since there is only one definition given, it has to be better than the ones which are not even featured!
When rolling a regular die what is the probability of getting an even number?
The sample space is 1, 2 3, 4, 5, & 6. Since three of the aforementioned numbers are even (2, 4, & 6), and there are 6 possible outcomes, the probability of an even number is 3/6 or 1/2.
What is the experimental probability of rolling an even number?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling an even number is 3 in 6, or 1 in 2, or 0.5, but the experimental probability changes every time you run the experiment.
What is the probability of rolling an even number or a number less than 4?
The answer depends on what the experiment is.The answer depends on what the experiment is.The answer depends on what the experiment is.The answer depends on what the experiment is.
How do you calculate relative frequency probability?
You carry out an experiment repeatedly. Then the number of times that the selected even occurs divided by the total number of trials is the relative probability for that event.
Why is sample size important in determining probability?
The bigger the sample size the more accurate the results will be. For example, if you roll a 6 sided die and track the results to get the probability of rolling a six. If you only roll 6 times, then you may not even get one 6 or you could get a few. A small sample size means you won't get very reliable results.
How do you find the experimental probability that a particular result will occur?
You carry out the experiment a large number of times. Count the number of times it was carried out (n). Count the number of times in which the particular outcome occurred (x). Then, the experimental probability for that even is x/n.
When Rolling a die 5 times and noting whether it is odd or even on each roll what is the size of sample space?
It all depends on what you do with the information that you note. If you count up the number of odds [or evens] in the five rolls, your sample space is {0,1,2,3,4,5} with size 6. If you look for whether you had more odds than evens your sample space is {Y,N}, with size 2. If you subtract the number of even outcomes from the number of odd outcomes, your sample space is {-5,-4,,...,4,5} which is of size 11.
Two dices are thrown simultaneously what is the probability that both the dices have even number?
The sample space is 62 or 36. Take the 1st die rolled. It must start with a 2, 4, or 6. Likewise, the 2nd die rolled must be a 2, 4, or 6. So, with the 1st die at 2, the 2nd die could be 2, 4, or 6. The same holds true for the 4 & 6. There are 9 possible rolls then that are even & even. The probability is 9/36 or 1/4.
What are cover-slips used for in an experiment?
cover slips are generally used with a microscope slide to press the water of the sample to a more even level so that the lens can focus properly and the sample you are studying doesn't move around as much.
When Something that has a even chance has a probability of?
It has a probability of 0.5
