Determine the missing probability value for the probability distribution. $$\begin{array}{|l|c|c|c|c|c|} \hline \boldsymbol{x} & 0 & 1 & 2 & 3 & 4 \\ \hline \boldsymbol{P}(\boldsymbol{x}) & 0.07 & 0.20 & 0.38 & ? & 0.13 \\ \hline \end{array}$$

Question 73. Complete the pdf and answer the questions. In order to complete this, Pdf, we need to find the missing probability because all probabilities, some to one, we need to figure out that the probabilities that were given some to 90% in order to figure out our missing piece, we just simply subtract that 90% from one. We found that our missing piece is 0.1 to complete the third column. We just need to multiply the X values with their probabilities. Zero time, 0.30 one times 0.20 point two two times 0.1 Because you're a point, too. In three time 0.4, just 1.2. We have a question, eh? Find the probability that exit is too. Because we completed our pdf, you could just look in the table and find the probability of X B. And two is 0.1. Be buying the expected value they expected. Value is the summation. Every single ex multiplied with his probability. We've already done all of the X times the probabilities in the third column. So in this case, we're just simply adding together. The four numbers in the third column expected value is 1.6

Okay. We know that p of four is 0.2 and the sum of all the probabilities must be one. Therefore, p of X greater than two is your 20.6. So we're looking at P of three plus p of four. So we know that P A 40.2 if you have X is greater than two. Is your point sex?

We're gonna be looking at Problem nine of Chapter five, Section two. In this problem, a survey was done on how many automobiles a family household owns, where the data of the surveys given our table here X being the number of automobiles that a family does own and p of X being the probability that a family owns at many automobiles. Eso, for instance, there's a 27% chance that a household owns only one car and a 1% chance that I household owns five cars. So what we want to do is find the mean variance and standard deviation of the state of Let's start off by finding the mean say that Mu is equal to one times 0.27 plus two times your 20.46 plus three times your point to one plus four times 0.5 and plus five times you're a 50.1 This ends up giving us a mean equal to 2.7 Next, let's take a look at the variance, so we get one squared times 0.27 plus two squared him zero point for six plus three squared times 0.21 plus four squared times 0.5 and plus five squared times your point 01 minus cooper, 2.7 squared. That gives us a variance equal to zero point seven six 51 And, of course, our standard deviation is gonna be equal to the square root of that. It's a square is 0.76 51 gives us a standard deviation equal to zero point 87 47 And that is the mean variance and standard deviation of this data. Thank you.

Mhm. According to the definition, the probability that the random variable X. Is greater than we called you, too, because The probability that equals two plus the probability the articles. Mhm. Which vehicles .05 plus .05 Read trickles .1. Mhm. Mhm. And the expectation he calls the south of exciting times its probability. And so there's Eco's zero times 0.8, last one times, mhm 0.1 plus two times .05 Plus three times .05. And this tickles .35 Yeah, participation.
