00:01 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 this question we will discuss about the cumulative distribution.
00:11 And let me remind you that the cumulative distribution, c, b, f, it will be the probability of, it will be denoted by the capital f x, it's equal to little small x here, it is equal to the proper particular capital x small equal to small x.
00:35 So in this question we're given the x, it will be the final temperature conditions and it has only three values, 266, 271, and for each value of the x, that is the frequency for each value, so 48, 60 and 92.
00:57 Now to the next time i will compute the total.
01:00 So if we do the total, we have the 48 plus 60 plus 92, equal to the 200 here.
01:10 The next time i will compute the probability here...
