Probability

What is probability?

Probability tells us how likely something is to happen based on the frequency of it happening in the past. 

P(1) =P(2) = … =P(6) = 1/6 

If I throw the dice, I cannot predict which number will come up. However, if I throw the dice many times and check the number each time, I will see that each number comes approximately the same number of times (if the dice has not been tampered with). So, each of the 6 numbers comes up in about 𝟏/𝟔 of the cases – this is the probability (how likely it is) to come up. 

Probability of a specific outcome = (number of times outcome)/ (number of times occurrence) 

Probability is always between 0 and 1. It can be represented as a fraction, as a decimal number, or as a percentage (from 0% to 100%).
