उत्तर
Total number of outcomes = 5
Favourable number of outcomes of getting a green sector = 3
Favourable number of outcomes of getting a non-blue sector = 4
Thus, probability of getting a green sector
= `"Favourable outcomes of gatting a green sector"/"Total number of outcomes" = 3/5`
Probability of getting a non-blue sector
= `"Favourable outcomes of getting a non-blue sector"/"Total number of outcomes" = 4/5`
