Bronson is ordering nachos at a restaurant, and the server tells him that he can have up to five toppings: black beans, pico de gallo, green chiles, onions, and salsa. Since he cannot decide how many of the toppings he wants, he tells the server to surprise him. If the server randomly chooses which toppings to add, what is the probability that Bronson gets just pico de gallo, onions, and salsa? Express your answer as a fraction or a decimal number rounded to four decimal places.
