The corporations in the highly competitive razor blade industry do a tremendous amount of advertising each year. Corporation G gave a supply of three top-name brands, G, S, and W, to a consumer and asked her to use them and rank them in order of preference. The corporation was, of course, hoping the consumer would prefer its brand and rank it first, thereby giving them some material for a consumer interview advertising campaign. If the consumer did not prefer one blade over any other but was still required to rank the blades, what is the probability that
a. The consumer ranked brand G first?
b. The consumer ranked brand G last?
c. The consumer ranked brand G last and brand W second?
d. The consumer ranked brand W first, brand G second, and brand S third?
