Question 2 Based on the data collected from 23 nights, what is the probability of at least one O-ring failing, regardless of temperature?
(Note: This probability is called an experimental probability because it's based on only 23 nights, which is a fairly small number of events. To get a
better approximation of the actual probability, we would need data from many more nights. Note also that even though there was O-ring failure
on seven flights, all of those shuttles returned safely.)
