In problem 110, we have a situation in which we have a geometric distribution with a probability of 17 .3, and we're asked to sketch your graph of the distribution of the discrete random variable x.
00:14
X can take on the values 1 all the way through infinity.
00:17
So we're going to look at 1 through 10, and then this would just move on forever with each bar getting smaller as they go.
00:28
So if you solve for the first event being a success, you'll get 17 .3.
00:46
And then if the second one is a success, the first one was a failure, the second one had success, you get approximately 14%, a little bit more than 14%.
00:59
Then as you go down, this is going to decrease at three, two failures, and then a success was almost 12%.
01:09
And four, we had three failures and one success.
01:14
Almost 10%.
01:16
And you can see the pattern now.
01:19
Five means we had four failures and the fifth one was a success.
01:27
And six, seven, just slightly over 5%.
01:39
And eight, almost 5%.
01:44
And nine, we're at almost 4%.
01:51
And then 10.
01:58
And this will continue on...
