Hi, i'm david and i'm here to have you answer your question.
00:04
Now let me bring up your question here.
00:07
In the question we are given x represent the difference between the number of the hat and the number of the tails obtained when a count is tossed n times.
00:18
And we want to know what is the possible values of the x.
00:22
Before i do this one, let's take one example where n equals to 3.
00:27
So when we toss the cone 3 times, there are certain.
00:31
The second outcomes here can be the hat, hat, hat, head, the head, head, tell, the head, tail, the tail, hat, hat, the head, tell, tell, tell, the tail, tell, the tell, tell, tell, and the tell, tell, tell, tell, so it could be eight total principal outcomes here.
00:56
If we call the x equal to the number of the hat, minus the number of the head, the tails.
01:03
So we see x can have the value let's say this one will be number of the head equal to three minus number of the tail equal to zero so equal to three.
01:13
For the second one, x it can be equal to the two minus one so equal to the one and for the next one we'll have something two minus one so equal to the one.
01:29
So this one's something x equal to the two minus 1 so equal to 1 and this one will be x equal to the 1 minus 2 so equal to minus 1 and then this one we will have x equal to the 1 minus 2 so equal to minus 1 same thing here and the last 1 x equal to the 0 minus 3 so equal to the minus 3 so we see here the principal value of the x in this particular example x can equal to the minus one...
