Hey there, welcome to numerade.
00:04
We are looking at the denver international airport, where 84 % of recent flights have arrived on time.
00:13
So if we look at our sample size here of 10 flights, what is the probability that all 10 of them arrive on time? so let's write down our probability here.
00:26
We're giving probability that 84 % of them, of the flights, arrive on time.
00:32
So in decimal form that would be 0 .84.
00:37
So this setup over here is a binomial set up.
00:40
So our equation here is the probability of the x, equalling sample size and x for combinations, probability raised to the x times q raised to the n minus x.
00:56
So we want to see that all 10.
00:58
So we 10 out of 10...
