Can Probabilities take on negative values only when the events are occurring less than 50 percent of the time?

Probabilities can never be negative. A probability distribution is defined as follows:
- Every event has a probability of occurring between 0 and 1, inclusive.
- The sum of the probabilities of each event occurring is 1.

Is it true that two dependent events can have the same probability of occurring?
Yes, it is possible for two dependent events to have the same probability of occurring. The probability of an event is dependent on the outcomes of other events, and it is influenced by the relationship between these events. So, it is conceivable for two dependent events to have equal probabilities.
How can you find the probability of two mutually exclusive events?
The calculation is equal to the sum of their probabilities less the probability of both events occuring. If two events are mutually exclusive then the combined probability that one or the other will occur is simply the sum of their respective probabilities, because the chance of both occurring is by definition zero.
What function do you use to calculate the probabilities of compound events?
To calculate the probabilities of compound events, you can use the multiplication rule or the addition rule, depending on whether the events are independent or mutually exclusive. The multiplication rule is used when the events are independent, and you multiply the probabilities of the individual events. The addition rule is used when the events are mutually exclusive, and you add the probabilities of the individual events.
How are probabilities of independent events alike?
They are not!
How do you teach probability of independent events?
Two events are said to be independent if the result of the second event is not affected by the result of the first event. Some common ways to teach this are to perform simulations with coin flips.Students need to understand that if A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.Students can predict and then observe probabilities of a fixed number of heads or tails.This lets then see the ideas in action.
What is the probability of the multiple of three?
Things and numbers don't have probabilities. Situations and events that can happen have probabilities.
Can unknown events change probabilities?
Yes
How do you get probabilities of situations that contain multiple events?
The answer depends on if and how the events depend on one another.
How do you find the probability of an event followed by another event?
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
Which distribution is used to find probabilities about the number of independent events occurring in a fixed time period with a known average rate?
The Poisson distribution. The Poisson distribution. The Poisson distribution. The Poisson distribution.
What are dependent and independent probability in math terms?
Two events are said to be independent if the outcome of one event does not affect the outcome of the other. Their probabilities are independent probabilities. If the events are not independent then they are dependent.
Can Probabilities be added when events are independent?
Yes. no its not its false :from Scott Powell
