d. The probability that the wave will crash onto the beach between 1.5 and 1.8 seconds after the person arrives is P(1.5 < x < 1.8) = e. The probability that it will take longer than 1.7 seconds for the wave to crash onto the beach after the person arrives is P(x > 1.7) = f. Suppose that the person has already been standing at the shoreline for 1.1 seconds without a wave crashing in. Find the probability that it will take between 1.9 and 2.3 seconds for the wave to crash onto the shoreline.

How do you do parts d,e, and f?
Today, the waves are crashing onto the beach every 4 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
seconds. Round to 4 decimal places where possible.
c. The probability that wave will crash onto the beach exactly 2.1 seconds after the person
arrives is P(x = 2.1) = 0
d. The probability that the wave will crash onto the beach between 1.5 and 1.8 seconds after the
person arrives is P(1.5 < x < 1.8) =
e. The probability that it will take longer than 1.7 seconds for the wave to crash onto the beach
after the person arrives is P(x > 1.7) = |
f. Suppose that the person has already been standing at the shoreline for 1.1 seconds without a
wave crashing in. Find the probability that it will take between 1.9 and 2.3 seconds for the
wave to crash onto the shoreline.
