Verify that the following function is a probability mass function, and determine the requested probabilities. f(x) = (216/43) (1/6)*, x = {1,2,3) Round your answers to four decimal places (e.g. 0.9876). Is the function a probability mass function? (a) P(X ≤ 1) = i (b) P(X> 1) =i (c) P (2 < X < 10) =

Please do not give solution in image format thanku The local amusement park was interested in the average wait time at their most popular roller coaster at the peak park time (2 p.m.). They selected 13 patrons and had them get in line between 2 and 3 p.m. Each was given a stopwatch to record the time they spent in line.
