Mr. Ramos is holding five cards numbered 1 through 5. He has asked five students to each randomly pick a card to see who goes first in a game. Whoever picks the card numbered 5 goes first. Justin picks first, gets the card numbered 4, and keeps the card. What is the probability that Jessica will get the card numbered 5 if she picks second?

1/4, because since Jusin had picked one, let'sreduce it the items to be chosen. One person who will pick will be instead 1/4. The less items, the greater the chance.
