cars in a town have 4digit numbers.What is the probability that the number of the car we first met when we went out early in the morning was a happy number?

note:when the happy number is mentioned,it should be understood that the sum of the first two digits of the car's number is equal to the sum of the last two digits.

Probability in mathematics refers the extent to which an event likely to occur. The number of possible chances to occur in an event is called Probability. The examples of probabilities are tossing a coin ( Head or tails), Die. Measures the likelihood of an event by using the way :- P(A) > P(B).

Probability is the term, used in Mathematics, which says about the chances of happening the Event. It is used everywhere in our life.

Probability is the number of ways of achieving success. The total number of possible outcomes. For example, the probality of flipping a coin and it being heads is 1/2, because there is 1 way of getting a head and the total number of possible outcomes is 2.

 First you have to know what probability means. Probability means yes or no  that means those are two characters in one object which is equal to a half. For example a coin has two sides which are tail and head so it you choose tail the probability will be 1/2 and  if you choose head the probability will also be 1/2.

So  to answer the question the probability of the happy car number is 1/2.

The following below is how I  got the answer

x+x=x+X

2x=2x=1x

1x is the probability of all these cars that you mate.

So for the happy number will be 1/2

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0...

Probability is a chance factor occurs at every outcome. nothing but divide the number of events with Number of possible outcomes this will give a single value that is known as probability. Probability value all ways lies between 0 and 1

For example: what is the probability to get rain tomorrow by using past data

Probability is the livelihood of an event occurs. This event could be randomly selecting the ace of spades, or randomly selecting a red sock or a thunderstorm. Every possibility for an event is called an outcome.

Probability denotes the possibility or extent of an event to occur. If consider in specially in mathematics context, so the value of probability can not go beyond 1.

Probability is a part of mathematics relates to numerical descriptions of how likely an event is to occur. The probability of an event is determined by a number between 0 and 1.0 indicates impossibility of the event while 1 indicated possibility of an event. Probability is never above 1 Or below 0.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment. To find the probability of a single event to occur, first, we should know the total number of possible outcomes.

Probability Definition in Math:

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it. Probability can range in from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event. Probability for Class 10 is an important topic for the students which explains all the basic concepts of this topic. The probability of all the events in a sample space adds up to 1.

For example, when we toss a coin, either we get Head OR Tail, only two possible outcomes are possible (H, T). But if we toss two coins in the air, there could be three possibilities of events to occur, such as both the coins show heads or both show tails or one shows heads and one tail, i.e.(H, H), (H, T),(T, T).

Formula for Probability:

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event to happen P(E) = Number of favourable outcomes/Total Number of outcomes

Sometimes students get mistaken for “favourable outcome” with “desirable outcome”. This is the basic formula. But there are some more formulas for different situations or events.

In mathematic it is refers as the chances of occurrence of any event it varies from 0 to 1   . it it hard for some but for some uth us very easy  to solve such question you just need to connect the problem to your daily life \ practical life and then you can solve uth easily.

PROBABILITY IS A DISCIPLINE OF MATHEMATICS CONCERNED WITH NUMERICAL EXPLANATION OF THE LIKEHOOD OF AN EVENT OCCURRING OR THE TRUTH OF A CLAIM. THE PROBABILITY OF AN EVENT IS A NUMBER BETWEEN 0 AND 1, WITH O INDICATING IMPOSSIBILITY AND 1 INDICATING CERTAINTY.

the probability of the number we first met when we went out early in the morning being a happy number is 1 in 4 because each number in a town has 4 digits.

The probability is 9/10 if we go early in the morning, while the probability remains 9/9 if we go during the day.
