A new car is sold with or without antilock brakes, with or without a Cd player, with or wothout electric seats, and with or without a sunroof. How many different choices are there??


A new car is sold
with or without antilock brakes, 2 choices
with or without a Cd player, 2 choices
with or wothout electric seats, 2 choices
and with or without a sunroof. 2 choices
How many different choices are there??

So 2*2*2*2=16 different choices possible.
