Step-by-step explanation:
Using it's concept, it is found that there is a 0.64 = 64% probability that neither flight is delayed.
<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, there are 2 flights, each with a 0.8 probability of being on time. The flights are independent, hence the probability that both are on time is given by:
p = 0.8 x 0.8 = 0.64.
