At a certain airport, 65% of the flights arrive on time. A sample of 10 flights is studied. Find the probability that all 10 of the flights were on time.

So, the probability is P=0.0135.

Step-by-step explanation:

We know that at a certain airport, 65% of the flights arrive on time.

We get that p=0.65 and q=1-0.65=0.35.

We have 10 flights, so n=10.

We calculate the probability that all 10 of the flights were on time, so k=10.

We use the formulu:

we get:

So, the probability is P=0.0135.
