You have been cycling around Europe with friends and are returning home. Your friend is nervous about catching a ferry from Calais.

How likely is it that the ferry will sink?

As part of the return journey home, you need to catch a train. For the journey, you have packed sandwiches.

There are 2 ham sandwiches, 2 peanut butter sandwiches and 4 cheese sandwiches.

If you pick a sandwich at random, what are the chances of picking a cheese sandwich?
