Ex 4.2, 5 If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a non blue sector? Total Sectors = 5 Number of Green Sectors = 3 Number of Red Sector = 1 Number of Blue Sector = 1 Probability of getting a Green Sector = (ππ’ππππ ππ πΊππππ ππππ‘πππ )/(πππ‘ππ π πππ‘πππ ) = π/π B means Blue Sector R means Red sector R means Green sector Number of Non Blue Sectors = Number of Total Sectors β Number of Blue Sectors = 5 β 1 = 4 Probability of getting a non Blue Sector = (ππ’ππππ ππ πππ π΅ππ’π π πππ‘πππ )/(πππ‘ππ ππππ‘πππ ) = π/π
