Using it's concept, it is found that there is a 0.3043 = 30.43% probability of at least one O-ring failing.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, of the 23 flights, 7 had at least one failure, hence the probability is given by:
