Answer 1

Answer:

What is the Probability ?

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

The value is expressed between zero and one.

Formula:

$\bf\blue{Probability = \frac{Number\:of\:favourable\:outcomes}{Total\:Number\:of\:outcomes} }$

Example:

• Why is tossing a coin considered to be a fair way of deciding which team should get the ball at the beginning of a football game?

Solution:

Tossing of a coin is a fair way of deciding because the number of possible outcomes are only 2 i.e. either head or tail.

Since these two outcomes are an equally likely outcome, tossing is unpredictable and is considered to be completely unbiased.

_____________________________________

The probability of all the events in a sample space sums up to 1.

Answer 2

Answer:

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 indicates impossibility of the event and 1 indicates certainty.
