# What is Probability and Statistics ?

Probability is the study of the chances a particular event has, as any event happening has certain outcomes. So the measure of probability ranges from ‘0’ (event not happening-0%chance) to ‘1’ (event happening for sure-100%chance).

Example:

Example: A dice is rolled in a game. Probability of getting the number ‘3’ is?

Total outcomes for dice=6

Getting ‘3’ is like 1/6 chance.

P(3)=1/6

Example: In a bag, there are 4 oranges, 5 apples and 6 plums. Probability of picking an orange is?

Total outcomes from the bag -> 4+5+6=15

Number of oranges=4 -> P(orange) = 4/15

Statistics is the study of organizing, analyzing, and interpreting data collected and using this information in order to carry out surveys and experiments.

Mean, median and mode are used to find average of the information

Example: Find mean, median, mode for the following:

2,3,4,6,3,6,2,7,3

Mean=(2+3+4+6+3+6+2+7+3)/9)=4

Median: First write in order -> 2,2,3,3,3,4,6,6,7

Median-> 3

Mode -> 3(most repeated number!)
