A problem in mathematics is given to three students $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and their respective probability of solving the problem is $\frac{1}{2}, \frac{1}{3}$ and $\frac{1}{4}$. $[2002]$ Probability that the problem is solved, is: (A) $3 / 4$ (B) $1 / 2$ (C) $2 / 3$ (D) $1 / 3$

Problem. 14 is dealing with freshman GP eight and the problem gave us 36 individual GPS. That's a sample from the freshman population, a standard deviation of 0.62 And so, with the information given, we have to determine the sample mean the sum of all the GP is given is 101.5, and we need to divide that by the total number of GP is given just 36 that gives us two point A to each GP. A given had just one decimal, and when you're given raw data, your round up your mean by one extra decimal than given and where X to estimate the true mean GP of the freshman class been 99% confidence level. We then need to determine the Z Valley that's associated with a 99% confidence level, and that's 2.58 We will now use the falling to construct our confidence interval, and we just need to plug the values in. So we have 2.2 plus and minus 2.58 multiplied by 0.62 divided by the square root of 36. I would then end up with 2.82 plus and minus zero point 27 and I will use this information to construct my confidence interval. On the left side, I'll have 2.8 to minus is your 0.27 and on the right I'll have 2.82 plus 0.27 My true mean of GP is between 2.55 and 3.9

So in the given question we are told that there is a problem that is given to three students A. B and C. And it is told in the question that the olds in favor of the aunts and favor of each of these students solving the given problem is three is 274 A. It is four S. 264 B. And it has two is 284 C. And we are told to find the probability that the problem is solved. Probably think that the problem is solved. So we can take the probability that A solves the problem. Air Science as three divided by three plus seven which would give us the property us three by 10. Next we have the probability that be solves the property that these souls which can be found by taking four divided by four plastics which is equal to four by 10. And lastly we have the probability that see solves the question the problem. So two divided by two plus eight gives us the priority has to buy 10. So now we have the probabilities of a B and C separately if they solve the problem and we are asked to find the property probability when the problem is solved by anyone. Right? So we can take this probability by taking one minus the probability of the problem not being salt. If the problem is not being solved by anyone bye anyone buying no one. We can take this probability by taking the compliment of a BNC. Right? So if you take the compliment of a BNC we can find the probability of the problem being solved by subtracting it from one. So P of a compliment times pay of big compliment times pay off. See compliment yeah would give us one minus we have a compliment is one minus three by 10 which is seven by 10. Be a big compliment. This one minus four by 10 which is six by 10 and PFC complement this one minus two by 10 which is eight by 10. So if we know the subtraction what we get as the probability is 83 divided by 125. So now we can look at the options and in the option the option e gives us the answer has 83 divided by 1 25 which is the correct option. So I hope you understood the method. Thank you.

Okay, so you're playing a role, that table. And so the chances that you get the right lawn gives you a payout of $36. But since you're paying the dollar to get it, you're winning 35 and you have a one out 38 chance choosing the right slot, and then you lose a dollar. If you guess the wrong one, just gonna be 37 out three a. So then that's gonna end up giving you negative zero point 05 to 6.

So we want to find the students grade point average rounded to the nearest 1000 based on this class list this report card we seen So there's a couple things we need to do. First of all, we need to figure out how many total credits there are, and then we're gonna figure out how many total grade points there are. Then I would take those great points and dividing by the number of credits. So to find the credit total, you're just gonna take this middle column and add them all together. We're going to three plus three plus three plus four, so that should be 13 total credit hours. Next, I want to take the grade and the credits and combined those. So we're gonna be combining this way to make the total grade points. So the grade points. So here's what you gonna do for the great points. We want to know how much it's worth. And then how many hours it waas So you're great point scale goes a is a 4.0 A B plus is a 3.5 B is a three and then so on and so forth. C plus would be 2.5 and then just follow that pattern, moving down by the haps. So a B is three points and we had three hours of it. All right, we're going to three times three on that one. For English. A C is only two points, and then there were three credit hours there for history to be plus, so it's 3.5 points for three credit hours, and then the best when we have here is chemistry. It's an A. So it's a four point. Oh, and there were four hours of it. So now we can make each of these into a number total. We're gonna just add all these together to figure out the total number of great points. So each of these making them into a number, answer here. If I total these together, then the number of grade points is 41.5 for this particular student. So now to figure out your G p A, we take the number of grade points 41.5 and divide them by how maney credit hours that were so dividing it by 13. And when I take those together I get 3.192 because I wanted to round it to the 1000 which is the third decimal place
