a. The variables in Exercise 5.3 are either discrete or continuous. Which are they and why? b. Explain why the variable "number of dinner guests for Thanksgiving dinner" is discrete. c. Explain why the variable "number of miles to your grandmother's house" is continuous.

Problem. One, uh, discreet friend and variable are restricted to define separate values or example, integers or or counts, and that continues from them valuable. So this is the district, and the continuous front and valuable are not restricted to define separate values but can, uh, value over a continuous range. For example, listen a rational number or or re number? So four point A. I went to use discrete since the number off traffic. If activities are pounds for kitchen B, I choose continuous, since the distance can take on the similar values, which in a scene I chose continuous since the time can take on this male values, which indeed I choose discreet. Since the number of chips are cows, kitchen E I choose continues sense in the way it can take any decision values.

Now here. In this problem, we want to determine if each of the given situations representatives discrete, random variable for a continuous random variables. It's important to note that to the difference between the two. A discrete, random variable is something that can be counted. And then on the flip side, a continuous random variable is something that must be measure enough. That is the difference between the two. Discrete is something that must be counted. Continuous is something that must measure. Now let's run through these situations here on part A. We have the number of light bulbs that burn out in the next week in a room with 20 bulbs. Obviously, that's something that we're going to count. And so it's something that must be counted, and that is a discrete, random berg. Mhm, yeah, on Part D the time it takes to fly from New York City to Los Angeles. Well, that is something that must be measured. You have to measure the amount of time it takes, and so because that must be measured, that means that it represents a continuous random variable, mhm and see. We want the number of hits to a website in a day, and since you would count the number of hits, that means that the number of hits is discreet and the last thing on part D the amount of snow in Toronto. During the window you measure the amount of snow or the amount of rain that is measured, and so since it is measured, that makes us a continuous random variables.

Welcome to New Merida in the current problem. We are given a few variables and we have to find out if those will be discrete or continuous. So the number of light bulbs mm that burn out in the next. That Burnham. Yeah. Let's vic yeah. In a room off in a room of 20 bulbs. Okay. The second variable is the time taken, the time taken to fly from New york city two Los Angeles and the 3rd 1 is uh huh. Number of hits, number of kids to our website to uh website in the day. and # four is the amount of slow amount of snore in toronto. In torrent job you're innovator. Now we have to determine which of these will be descript and which of these will beagle two years. So to start with, if we see the number of light bulbs that that will burn out in the next week in a room with 20 bucks now imagine through there are 20 bumps and it is possible that it will be 20 bulbs that all On for at us. It can be seven. It can be fired. It can be zero. It can be one. It can be 13. It can be any number. Right? But you know what will be that number? It's like Unique discrete values, correct? You can say it is 15 or you can say 17 or you can even say 20. But these are all discrete values. It will never be like 17.5 light bulbs where I'm burned out. Right? Therefore he can call this to be our discrete random variable this bit in this case no time taking. So I'm taken to fly now. I understand time is a very continuous process. Well I'm telling maybe you can you can have really accurate measurements of time. But I think this hour minute all these things, these are human meat. Just like the number of bulbs that Elsa human made. But you can definitely say that it is going to be four bucks or five bucks. Can you say like, okay, it will exactly take four hours. You know, it can be four hours and Jill Maynard's husband or somewhere. Four hours and three minutes as well correct. Or four hour, 2.5557 Anything. So this time is a very continuous process. And hence it will their continuous variable next the number of hits to our website ability. Again, then you're considering number of hits to the website. Suppose your website is very famous and he's getting something around uh, patriots ready. Okay. And, and once this 30 hits are achieved. Weekend, mm hmm. Weekend. Uh, call that these tattooed hits are uh, achieved on a particular day. And it could be 31 as well. You can see what will be the next number, What will be the next number, get it. So even if it gets 399 hits, you can still say what will be the next hit. One more person visits. So it is going to be discreet in nature and hence we right discrete. And the next one is the amount of snow. Now again, when it is amount of snow. Okay, So we know we measure it that in interest millimeters micro millimeters nana millimeters. But no matter what, it is never possible to accurately measure the entire amount of snow. So again, this is going to be continously needed. So hope you could understand it. Let me know if you have any questions.

Which in two, um, question A. I will choose continues, since the speed can take this event values, which is being, I will choose discreet, since the age is a Boston integer, which in C I will choose discrete senses the number off books or comes which, indeed I will choose continues this sense of the way it can take on this image values coaching E. I will choose this creek, since the number off lightning strides are counts.
