If the result of the experiment is not known then it is known as a random experiment.
If we throw a dice then the result could be any number from 1 – 6.
When we do an experiment then there could be different results, these possible results of the random experiment are called outcomes.
There are two possible outcomes when we toss a coin i.e. head and tail.
Equally Likely Outcomes
If every outcome has the same possibility of occurring these outcomes are called Equally Likely Outcomes.
If we throw a dice then there is an equal chance of every no. to come while doing the random experiment. i.e. a dice has the same possibility of getting 1, 2, 3, 4, 5 and 6.
Linking Chances to the Probability
What is the chance of getting 3 when we throw a dice?
There is only one chance to get 3 in one throw and the total possible outcomes are 6.
Hence the probability of getting .
Outcomes as Events
Each outcome or collection of outcomes of an experiment is known as an event.
If we throw a dice then getting each outcome 1, 2, 3, 4, 5 and 6 are events.
What is the event of getting odd numbers when we throw a dice?
The probability of getting an odd number is 3(odd numbers are 1, 3, 5)
The total number of outcomes is 6. The probability of getting an odd number .
