Probability as a number lies between 0 and 1 .

A probability of 1 means that **the event will happen**. If the probability of a road traffic accident was 1 there would be nothing you could do to stop it. It will happen.

A normal distribution with a mean of 0 and a standard deviation of 1 is called a **standard normal distribution**. Areas of the normal distribution are often represented by tables of the standard normal distribution.

Probability is **the measure of the likelihood of an event to occur**. Events can't be predicted with certainty but can be expressed as to how likely it can occur using the idea of probability.

Events that are certain: **If it is Thursday, the probability that tomorrow is Friday** is certain, therefore the probability is 1. If you are sixteen, the probability of you turning seventeen on your next birthday is 1.

Let us now practice using the axioms by proving some useful facts. Using the axioms of probability, prove the following: For any event A, P(Ac)=1−P(A). The probability of the empty set is zero, i.e., **P(∅)=0**.

What is the probability formula? The formula for probability states that the possibility of an event happening, or P(E), equals the ratio of the number of favorable outcomes to the number of total outcomes. Mathematically, it looks like this: **P(E) = favorable outcomes/total outcomes**.

01 is **undefined**.

If a baseball player goes up to bat 100 times in a season and gets a hit 70 of those times, they are likely to get a hit the next time they go up to bat. Statisticians calculate a team's probability throughout the season, allowing them to make somewhat informed guesses about whether a team is likely to win a game.

The total probability of a set of related events sums up to 1 **because the probability of each individual event in the set is a fraction of the whole**.

Answer. **Yes.** **1/3 can be the probability of an event** as the probability of an event always lies between 0 and 1 and 1/3 = 0.33, which is between 0 and 1.

Mean is the average of the data that can be calculated by dividing the sum of the data by the numbers of the data. **The mean of any normal distribution is not zero**. However, we can normalize the data so that it has zero mean and one standard deviation, that is called as standard normal distribution.

**An event that always occurs has a probability of 1** .

EXPLANATION: Ward-Leonard method of speed control is achieved by **varying the applied voltage to the armature**.

**Phase acts as main supply line while neutral acts like a return path for the circuit to be completed**. Phase has some potential value but neutral has zero potential value in normal condition. In the case of fault condition or Short Circuit there is flow of Current and voltage from neutral.

**Evolution** is a unifying theme of biology because it accounts for both the diversity and the similarities, or the unity, of life. As you study biology, you will see time after time that organisms are related to one another.

Answer. (a) Motion: **An object is said to be in motion when its position changes with time**. We describe the location of an object by specifying a reference point. Motion is relative. The total path covered by an object is said to be the distance travelled by it.

**No single person or organisation controls the internet in its entirety**. Like the global telephone network, no one individual, company or government can lay claim to the whole thing. However, lots of individuals, companies and governments own certain bits of it.
