Okay, so i see that you need help with this problem, and it states, according to a recent survey, 81 % of adults in a certain state have graduated from high school.
00:12
So 81 % have graduated.
00:20
If 15 adults from the state are selected at random, so 15 are selected at random, what is the probability that five of them have not graduated from high school? so if 81 % graduated, then that means that 90, i'm sorry, 19 % have not graduated.
01:03
Now, let's take a look at the list of choices.
01:06
So i'm automatically going to get rid of a because 20 is not in the play.
01:12
Because we're not adding 15 plus 5.
01:18
It's 5 out of the 15.
01:20
Now, let's take a look at the next options.
01:24
So i can see why they would have 10 have graduated in 5 of not for these...
