Choosing the first tile:


At first, there are 7 tiles.

You are interested in choosing a 5. There is only one tile with a 5.

p(5) = 1/7



Choosing the second tile:

After the 5 has been taken, now there are 6 tiles left.

Only one tile has the number 6.

p(6) = 1/6


The overall probability of choosing a 6 after a 5 is the product of the individual probabilities:


p( 5 then 6) = 1/7 * 1/6 = 1/42


Answer: The probability of choosing a 5 and then a 6 is 1/42
