Detailed Solution

Total number of green sectors= 3

Total number of blue sectors= 1

Total number of red sectors= 1

Total number of sectors = $3 + 1 + 1 = 5$

Probability of getting a green sector= $\frac{T o t a l n u m b e r o f g r e e n s e c t o r s}{T o t a l n u m b e r o f s e c t o r s}$ $= \frac{3}{5}$

Total number of non blue sectors= Total number of sectors - Total number of blue sectors = 5 - 1 = 4

Probability of getting a non blue sector= $\frac{T o t a l n u m b e r o f n o n b l u e s e c t o r s}{T o t a l n u m b e r o f s e c t o r s} = \frac{4}{5}$
