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

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 :)

That is the answer to your question
