Question

Today, the waves are crashing onto the beach every 5.8 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 5.8 seconds. Round to 4 decimal places where possible.

The probability that the wave will crash onto the beach between 0.9 and 3.4 seconds after the person arrives is P(0.9 < *x* < 3.4) =

Find the minimum for the upper quartile. seconds.
