    here's a relatively easy one:

    You are screened for a disease that strikes one out of every 500 people.

    The screening test has a false positive rate of 5%.

    If you test positive, what is the actual probability of your having the disease?

    lack of oxygen and rapid cooling of existing fuel/oxidants bellow activation temperature, but mainly lack of oxygen?

  8. When a ship displacing 500T, pulls into a lock, and it takes 700,000 cubic meters of water to lift it 30ft

    How many cubic meters of water will it take to lift a boat displacing 15T the same height, in the same lock?
