(a)
To complete: The table of values of buyers of a certain model of car.
(b)
To find: How many buyers were surveyed.
(b)
To find: How many buyers were surveyed.
(c)
To find: How many bought a new car and were satisfied.
(d)
To find: How many were not satisfied.
(e)
To find: How many bought used cars.
(g)
To find: How many were not satisfied had purchased a used car.
(g)
To rewrite: The event “How many were not satisfied had purchased a used car” using the term given that.
(h)
To find: The probability of the outcome in parts (f) and (g).
(i)
To find: The probability that the used car buyers is not satisfied.
(j)
To explain: The reason why the answers of the parts (h) and (i) are different.
(k)
Whether the events “car is new” and “the customer is satisfied” are independent.
