1. If P(A) 20.5, 19(3) 2 0.3,and P(A 0 B) = 0.15 are events A and B independent? (write "Y" or "N"). 2. If P(A) = 0.6, P(B) = 0.5,and P(A U B) = 0.8 find P(A 0 B) and determine if events A and B are independent? (write "Y" or "N"). 3. |fP(B IA) 2 0.2, P(A) = 0.5, and P(B) = 0.3. find P(A 0 B) and determine if events A and B are independent? (write "Y" or IINII). To judge independence you can calculate this equation: P(A) -P(B) = P(A n B) . If this equation is true (both sides are equal) then the events are said to be independent. \"You need to memorize this rule!\" student.desmos.com
