question_answer 1)

                If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a non blue sector?

Answer:

                There are in all 3 + 1 + 1 = 5 outcomes of the event. \[\therefore \] Probability of getting a green sector. Getting a green sector has 3 outcomes as there are in all 3 green sectors \[=\frac{3}{5}\]                 Getting a non blue sector has 3 + 1 = 4 outcomes as there are 3 green (non blue) sectors and 1 red sector \[\therefore \] Probability of getting a non blue sector \[=\frac{3+1}{5}\] \[=\frac{4}{5}\]
