# Long description

A diagram that shows the probability of different events. It shows a scale from impossible on the left to certain on the right. Events are labelled above the scale, and the corresponding percentage probability is shown below the scale. The probabilities and events shown are: the probability that a clover has four leaves is 0.01 per cent; the probability of getting struck by lightning is 0.0033 per cent; the probability a person is left-handed is 10 per cent; the probability that it will rain on a given day in the UK is 33 per cent; the probability of a fair coin toss landing on tails is 50 per cent; the probability that a baby will be a boy is 51 per cent; the probability of surviving an aeroplane crash is 95 per cent.
