In this question, you look at a survey in the united states.
00:04
So it turns out that the probability that an american citizen is a liberal has the probability 0 .3, okay, this is a liberal.
00:14
And conservative, the probability that's 0 .55.
00:19
And, you know, another case, another case is actually given by 0 .15.
00:26
So now imagine you randomly select 10 americans, 10 persons, right? and you asked a few questions about this.
00:37
The first one says, what's probability that four of the maliboros? and of course, that has to be 0 .3 to the power of 4, right? and times 1 minus 0 .3 to the power of 6, right? and the second question is, because this is simple binomial distribution, what is probability? that neither is conservative, neither is conservative, nothing is conservative.
01:01
So all of these are liberals or, you know, without opinion, right? another conservative, so of course is given by 1 minus 0 .55 to the power of 10, right? none of them are conservatives.
01:14
And finally, you also question, what is the probability that two are neither one nor the other, another one nor the other.
01:22
So two of them, right? two of them that's of course given by 0 .15 to the power of 2 and times 1 minus 0 .15 to the power of 8...
