So here in this question, we look at flights, right? according to the question, at a down for international airport, 84 % of the recent flights have arrived in time, right? now you look at a sample of 12 flights, then you ask a few questions.
00:22
First, we find probably that all of these flights were on time.
00:25
Well, obviously, that's going to be given by 84 % to the part of 12, because these flights are independent.
00:33
So it's given by 0 .84 to the part of 612, right? and then you will get that this to be actually not so small a number is about 0 .1, 2, 3, 4.
00:46
Okay, so that's about 12 .34%.
00:49
Find the probability that exact 10 of this on time, exact 10, right? so 10 of them, right? so 84 % to the power of 10, right? but two of them are not.
00:58
So that's 1 minus 84%.
00:59
That's 16 % to the part of 2...
