Expert Solution
Step 1

Probability: Probability helps in knowing the likelihood of occurring an event. For example, A customer wants to buy a car that has 6 different colors in the showroom. The probability of randomly buying either a black or a red car by the customer is:

P (black or red) = P (black) + P (red)= 16 + 16= 26= 13= 0.3333 or 33.33%

Hence, the probability of randomly buying a black or a red car is 0.3333 or 33.33%.
