In a certain parking lot all the cars are either red or blue. The total number of cars in the lot is cThe ratio of the number of red cars to the number of blue cars in the parking lot is a to bIf x is the number of red cars in the parking lot, which of the following can be used to find the value of x ?

I am looking down on a parking lot and can see that 10% of the cars are entirely white and 15% of the cars are entirely red. How would you estimate the probability that the next car to leave this lot will be entirely red or entirely blue? • Need more information to answer the question. • Add the two percentages and convert to a probability. • As many red cars are likely to leave the parking lot as blue cars and set the estimate at 0.5. • Multiply the two percentages and convert to a probability.
