Which of the following values Cannot be a probability of an event?

Which of the following values Cannot be a probability of an event?

Answer. Answer: the numbers greater than 1 and less than 0 cannot be a probability of any event.

What types of values Cannot be probabilities?

For example, the student says:

  • -1 and -0.5 cannot represent probabilities because a probability cannot be negative.
  • 4.2 cannot represent a probability because it is greater than one.
  • 0.6, 0.888, 0, and 0.39 can represent probabilities because they are between zero and one, inclusive.

Which can be the value of probability of an event?

In an experiment, the probability of an event is the likelihood of that event occuring. Probability is a value between (and including) zero and one. If P(E) represents the probability of an event E, then: P(E) = 0 if and only if E is an impossible event.

What is an event with a probability of 0 called?

An event with a probability of zero [P(E) = 0] will never occur (an impossible event). An event with a probability of one [P(E) = 1] means the event must occur (a certain event).

What does 0 mean in probability?

Chance is also known as probability, which is represented numerically. Probability as a number lies between 0 and 1 . A probability of 0 means that the event will not happen. For example, if the chance of being involved in a road traffic accident was 0 this would mean it would never happen.

Can probability density function be greater than 1?

A pf gives a probability, so it cannot be greater than one. A pdf f(x), however, may give a value greater than one for some values of x, since it is not the value of f(x) but the area under the curve that represents probability. On the other hand, the height of the curve reflects the relative probability.

What is the formula for calculating the probability of an event?

How to calculate probability

  1. Determine a single event with a single outcome.
  2. Identify the total number of outcomes that can occur.
  3. Divide the number of events by the number of possible outcomes.

What is the expected value of a random variable?

The expected value of a random variable is the weighted average of all possible values of the variable. The weight here means the probability of the random variable taking a specific value.

What is the range of a random variable?

The range of a random variable X, shown by Range(X) or RX, is the set of possible values for X. In the above example, Range(X)=RX={0,1,2,3,4,5}. The range of a random variable X, shown by Range(X) or RX, is the set of possible values of X.
