To find the probability of getting an even number (2, 4, or 6) between 2 and 4 times when rolling a fair die 8 times, we need to calculate the probabilities of getting 2, 3, or 4 even numbers and add them up.
The probability of getting exactly 2 even numbers is C(8, 2) * (1/2)^2 * (1/2)^6 = 28/256. The probability of getting exactly 3 even numbers is C(8, 3) * (1/2)^3 * (1/2)^5 = 56/256. The probability of getting exactly 4 even numbers is C(8, 4) * (1/2)^4 * (1/2)^4 = 70/256.
Adding these probabilities together, the probability of getting an even number between 2 and 4 times is (28 + 56 + 70)/256 = 154/256 = 77/128.

What does it mean if a number has a probability of 1?
If a number has a probability of 1 it means it is certain to occur.
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 measure of how likely an event will occur?
Probability is the measure of how likely an event is. ... The probability of event A is the number of ways event A can occur divided by the total number of possible.
The change that a given event will occur usually expressed between the number 0 will not and 1 the event will occur?
The chance that a given event will occur that is usually expressed between the numbers 0 and 1 is known as probability.
What is a number that describes how likely it is that a particular event will occur?
The probability.
The chance that a a given event will occur usually expressed between the number 0 will not and 1 the event will occur?
Probability
The chance that a given event will occur usually expressed between the number 0 will not occur and 1 the event will occur is called?
The chance that a given event will occur, usually expressed between the number 0 (will not occur) and 1 (will occur) is called probability.
The chance that a given event will occur usually expressed between the number 0 and 1?

A fair die is rolled nine times What is the probability that an odd number 1 3 or 5 will occur less than 3 times?
i dont know what the anser is sorry
What does it mean if a number has a probability of 1?
If a number has a probability of 1 it means it is certain to occur.
What is the ratio of the number of ways an event can occur to the number of possible outcomes?
The term is probability (theoretical probability), or how likely a given event is to occur.
A fair die is thrown What is the probability that a prime number will occur?
When a fair die is thrown the probability that a prime number will occur is 2:1
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.
There are 36 different outcomes possible when you toss two dice. What is the probability that the two dice will show the same number?
There are 6 different doubles that can be rolled. (They are 1 and 1, 2 and 2, etc.) You have a 6/36 chance of rolling doubles. The fraction 6/36 simplifies (reduces) to 1/6. Your 1 in 6 chance of rolling doubles now needs to be converted to probability. Probability speaks to the "chance" that something will occur. It is expressed as a "pure" number, and the range of probability is from 0 to 1. The probability 0 means that it cannot occur, and the probability 1 means that it will or must occur. Everything else falls in between. If you have a 1 in 6 chance of rolling doubles that translates into a 1 divided by 6 probability, or a 0.1666666... probability that a double will come up.
Is it true that the probability of an event is the number of ways it can occur divided by the number of times it cannot occur?
No.
