Question

Dotted part = 2

Shaded part = 3

Plain part =3

Answer 1

The probability of a sector type being chosen is = number of sectors of a particular type/ number of all sectors or simply the fraction of a particular type of sector.

For the dotted part: 2 dotted sectors/ Total of 8 sectors = .25 or 1/4 of the sectors are dotted
