Here's some more advice for you. Is there anything true about this advice?
Snakes on a plane:
When you're flying, always take a pet snake with you in your hand
luggage. The probability of there being TWO snakes on the plane is
almost zero, so you will be safe from snake attack.
Staying dry at the cricket
Follow the example of the famous mathematician Hardy and take an
umbrella with you to cricket matches. If you forget your umbrella
it is more likely to rain, so if you remember to take it with you
it is more likely to be sunny all day.
