  2. Serial order wise


Ex 5.3, 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 = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ πΊπ‘Ÿπ‘’π‘’π‘› π‘†π‘’π‘π‘‘π‘œπ‘Ÿπ‘ )/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘ π‘’π‘π‘‘π‘œπ‘Ÿπ‘ ) = 3/5 Number of Non Blue Sectors = Number of Total Sectors βˆ’ Number of Blue Sectors = 5 βˆ’ 1 = 4 Probability of getting a non Blue Sector = (π‘π‘’π‘šπ‘π‘’π‘Ÿ π‘œπ‘“ π‘π‘œπ‘› 𝐡𝑙𝑒𝑒 π‘ π‘’π‘π‘‘π‘œπ‘Ÿπ‘ )/(π‘‡π‘œπ‘‘π‘Žπ‘™ π‘†π‘’π‘π‘‘π‘œπ‘Ÿπ‘ ) = 4/5
