Two psychologists are studying the IQs of a group of business professionals.
• Let A be the event that a professional's IQ is greater than 115, with P(A) = 16%.
• Let B be the event that a professional's IQ is between 115 and 130, with P(B) = 14%.

chosen and one of their IQs is greater than 115 and the other is between 115 and 130?
