Answer

Total number of possible outcomes = 5

Number of favourable outcomes (Getting a non-blue sector) = 4 (3 green + 1 red sector)

P(Getting a non-blue sector) = Number of favourable outcomesTotal number of possible outcomes\dfrac{\text{Number of favourable outcomes}}{\text{Total number of possible outcomes}}

= 45\dfrac{4}{5}

Hence, the probability of getting a non-blue sector is 45\dfrac{4}{5}.
