Question: A computer store sells computers, monitors, printers. A customer enters the store. Let A, B, C be the respective events the customer buys a computer, a monitor, a printer. Assume the following probabilities:
· The probability P (AB) of buying both a computer and a monitor is 0.49.
· The probability P (ABCc) of buying both a computer and a monitor but not a printer is 0.17.
· The probability P (AC) of buying both a computer and a printer is 0.45.
· The probability P (BC) of buying both a monitor and a printer is 0.39
· The probability P(ACc V AcC) of buying a computer or a printer, but not both is 0.50.
· The probability P(ABc V AcB) of buying a computer or a monitor, but not both is 0.43.
· The probability P(BCc V BcC) of buying a monitor or a printer, but not both is 0.43.
