Question

The probablilty that andreas train is late is 0.05 work out the probablilty that her train isnt late?

Answer 1

Probability is always out of 1, therefore, you have to subtract 0.05 from 1.
1-0.05= 0.95
Therefore, the probablility that the train isn't late is 0.95 (or 95%)
hope this helps :)
