Question

You are given seven cards numbered 1 through 7. You shuffle the cards and deal them out on a table. What is the probability that the cards will be dealt in order: 1, 2, 3, 4, 5, 6, 7?

Answer 1

This is actually pretty easy!

P(Getting 1) = 1/7
P(Getting 2) = 1/6 (because we have a card less)
P(Getting 3) = 1/5
P(4) = 1/4
P(5) = 1/3
P(6) = 1/2
P(7) = 1

Answer 2

Now multiply all the P's.
