To model how long Amir will wait for a back-up using a continuous uniform distribution, save his lowest possible wait time as min_time and his longest possible wait time as max_time. Remember that back-ups happen every 30 minutes.

def sample_waiting_times(n_times):
  # Initialize waiting times
  waiting_times = []

  for _ in range(n_times):
    # Sample waiting time from the uniform distribution
    waiting_time = np.random.uniform(low=min_time, high=max_time)
    waiting_times.append(waiting_time)

  return waiting_times
