Hey there, welcome to numerate.
00:04
We were looking at the poll over here where adults who regret getting tattoos, right? so it is a survey that's saying 17 % of them who regret says there's too young that when they got their tattoos.
00:19
So with the range selected for adults and what's the probability that none of them say that they're too young to get tattoos? okay, so this will be part d or part a over here and we just did a binomial question over here, so this is the binomial probability equation.
00:37
So what we're going to do, we're going to list out what we have, probability, equals 0 .17.
00:48
We also have q, which is 1 minus p, so 1 minus 0 .17, will basically equal to 0 .83.
01:00
And with that, we also have a sample size of four of these adults here.
01:07
And x equals 0.
01:09
We could none of the select.
01:10
Says they are too young, right? so with this, we can plug into our equation here.
01:16
So we can put it down here.
01:18
P of x, so x is zero equals...
