Question Analysis
This question involves combining data from two frequency tables and calculating the probability of a specific event.
The main focus is on correctly adding up the frequencies of the desired category (white cars) from both tables and also finding the total combined frequency of all cars at both intersections to calculate the probability.

Key Concept Explanation
Probability of an event is calculated as the ratio of the frequency of the event to the total frequency.
When combining data from multiple sources, we sum up the relevant frequencies and the total frequencies across all the sources.

Step-by-Step Solution
First, find the total number of cars at Intersection A: .
Then, find the total number of cars at Intersection B: .
The combined total number of cars is
