Pat does a lot of travelling in her car, and she keeps records on how often she fills her car with petrol. The table alongside shows the frequencies of the number of days between refills. Estimate the likelihood that: a there is a four day gap between refills b there is at least a four day gap between refills. Days betweenrefills Frequency1 372 813 484 175 66 1
