Judge whether the statement is true or false
Write TRUE if the output of the expression is true and FALSE if the output of the expression is false.
Determine if the expression is true or false. A true expression is equivalent to one, a false expression is equivalent to zero.

If after 1969, print "Probably has seat belts.". If after 1992, print "Probably has anti-lock brakes.". If after 2001, print "Probably has airbags.". End each phrase with period and newline. Remember that print() automatically adds a newline. Ex: car_year = 1995 prints: Probably has seat belts. Probably has anti-lock brakes.arrow_forwardAssume test is a boolean variable and x is an int variable , which of the following is not a correct Boolean expression?
