Document Summary
A survey is made of a population to find out how many of them own a home, how many own a car and how many are married. Let h, c and m stand respectively for the events, owning a home, owning a car and being married. What do the following symbols represent: h mc, (h m)c, hc mc, (h m) c. Note that this is the same as the event (2). That is (h m)c = hc mc . (h m) c corresponds to owning a home or married and owning car. A b )c = ac bc (a b )c = ac bc. If you draw an m & m candy at random from a bag of the candies, the candy you draw will have one of the seven colors. The probability of drawing each color depends on the proportion of each color among all candies made. Here is the distribution for milk chocolate m & m"s:
