Christine Wong has asked Dave and Mike to help her move into a new apartment on Sunday morning. She has asked them both, in case one of them does not show up. From past experience, Christine knows that there is a $40 \%$ chance that Dave will not show up and a $30 \%$ chance that Mike will not show up.
