Here let we assume that let x denote the number of heads minus number of tails in the three tosses.
00:17
Number of heads minus number of tails in three tosses.
00:34
Then the sample points are our sample points will be here.
00:46
For head minus tail this is our column and this is net here and this will be our event in the three tosses so when we toss here let's the first in first here first toss it is our our in the three tosses the three are head then here head minus tail will be heads are three minus tail are zero that will be equal to here three and again here let comes head head and tail so here our number of head are two and number of tails are one so it will be one in next toss let it comes head, tail and head.
01:38
So here our number of heads are 2 minus number of tails are 1 that will be again 1.
01:44
Now in next toss let we get head and 2 tail.
01:50
Then here we'll be getting number of heads are 1 minus our number of tails tails are 2, that will be here, minus 1.
01:59
In next toss, let me get here, head, tail and tail.
02:06
So, here our number of heads are 1, minus our number of tails are 2, that will be again, here, minus 1...
