Nadia is ordering cheesecake at a restaurant, and the server
tells her that she can have up to five toppings: caramel, whipped
cream, butterscotch sauce, strawberries, and hot fudge. Since she
cannot decide how many of the toppings she wants, she tells the
server to surprise her. If the server randomly chooses which
toppings to add, what is the probability that Nadia gets just
caramel, butterscotch sauce, strawberries, and hot fudge? Express
your answer as a fraction or a decimal number rounded to four
decimal places.
