If we assume that the probability of an event occurring is 1 in 4 and that the event occurs to each individual independently, then the probability of the event occurring to one individual is 0.3955. In order to find this probability, we can make a random variable X which follows a Binomial distribution with 5 trials and probability of success 0.25. This makes sense because each trial is independent, the probability of success stays constant for each trial, and there are only two outcomes for each trial. Now you can find the probability by plugging into the probability mass function of the binomial distribution.

Why cannot a probability not be less than 0?
0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.
What is probability and how is it used in genetics?
Probability is predicting the chance of something happening. It can be used in genetics to predict traits we get. Like using punnett squares.
Can a probability be more than 1 or less than 0?
No. A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1. 0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.
Why can't probability be less than 0?
Because probability is measured from zero to one, where zero means something cannot happen and one meaning it will definitely happen. This can also be looked at as there being a 0% chance or 100% chance of it happening. So obviously there can not be less of a chance than it definitely not happening, so it cannot be less than zero.
What is probability explain conditional probability?
Probability is the chance of an event occurring. For example when flipping a coin you have a 50% chance that it will land on heads and a 50% chance that it will land on tails since there are only two possibilities.Conditional probability refers to when one event is dependent on another event occurring. It can also be written as the probability of an event B occurring after event A has already occurred. The notation for conditional probability is P(B|A). (Note: this does not mean B divided by A but probability of B after A)When two events are dependent, the probability of them both occurring is:P(A and B)=P(A)P(B|A)So for example: 53% of residents have home owners insurance. Of them, 27% has auto-insurance. If a resident is selected at random, what is the probability they with have both insurances?Let H stand for home owners insurance = 53% or 0.53Let A stand for auto insurance = 27% or 0.27P(H and P)=P(H)P(A/H)=(0.53)(0.27)= 0.1431So the probability of residents have both home owners and auto insurance is 0.1431 or 14.31%
What it the difference of Probability and odds.?
Probability is defined as the chance of something occurring in a non paranormal phenomena. Odd's are the chances of the Probability happening.
What is the chance of happening in science?
The chance of something happening can be called a probability.
What is probability of an impossible event?
If the event is truly impossible, it has a zero probability of occurring. The definition of impossible is "not able to occur, exist, or be done," so that means there's no chance of it happening.
Is the best definition of probability?
the extent to which something is probable; the likelihood of something happening or being the case. the chance that something will happen the likelihood of an event occurring

Do outcomes have the same chance of occurring?
No. Not all outcomes are equally probable. Generally, the chance, or probability, of a particular event happening can be calculated.It should be noted that the possibility of some events happening cannot be calculated.
The probability of this kind of event is 0?
If the probability is 0, the event has no chance of happening.
What does the math term Chance mean?
Chance is another word for the probability of an event occurring.
What is the number used to describe the chance of an event occurring?
It is the probability of that event.
What does the probability of 0.618 mean?
It means that there is a 61.8% chance of the event occurring.
Why cannot a probability not be less than 0?
0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.
What is mean by 1 in 6?
In probability this means that something has an 1 out of 6 chance in happening, or a 16.666...%
