Answers
Probability is the study of the chances of events happening.
Event:
A Possible outcome or combination of outcomes is called event.
The probability of happening our event always lies from 0 to 1.
The sum of all the probabilities of all possible outcomes of an experiment is 1.
Required probability=Number of trials in which the event E has happened/Total number of trials.
=========================================================
Solution:
Total no. Of sectors = 3 + 1 + 1 = 5
There are five sectors.
Three sectors are green out of five sectors.
Hence, P(probability of getting a green sector) =3/5
We will get a non-blue sector when we will get either a green sector or a red sector.
There is one blue sector out of five sectors.
Hence, Non-blue sectors = 5 – 1 = 4 sectors
Hence, P(probability of getting a non-blue sector) =4/5
