Step-by-step explanation:

The circle is divided into 5 sections. The probability that the needle lands on a particular color is equally likely.

   So,

        P(red) = \frac{1}{5}\\\\P(green) = \frac{1}{5}\\\\

   Probability of not blue = 1 - Probability of blue

                                      = 1 - P(blue)\\\\=1 - \frac{1}{5}\\\\= \frac{4}{5}
