i myopenmathlcom 'f Today, the waves are crashing onto the beach every 4.2 seconds. The times from when a person arrives at the shoreline until a crashing wave is observed follows a Uniform distribution from 0 to 4.2 seconds. Round to 4 decimal places where possible. a. The mean of this distribution is [:] d'l b. The standard deviation is C] d'l c. The probability that wave will crash onto the beach exactly 2.1 seconds after the person arrives is P(x = 2.1) = d'l d. The probability that the wave will crash onto the beach between 1.6 and 2.4 seconds after the person arrives is P(1.6
