In 2014 the probability that a randomly chosen electric car sold in the United States was manufactured by Tesla was $.30,$ while the probability that it was manufactured by Nissan was $.35 .^{42}$ What is the probability that a randomly chosen electric car was manufactured by neither company?
I'd probably just talk about a probability distribution on this problem. You know, outcome with probability and all I'm thinking about is if you have a general motors. So I married GM Is a point to 1 21%. And then Toyota because these things do not overlap. There is no way to have a genome. And the Toyota, That's .18. I would just say Make a 3rd column B other and then you can just say, okay, well these things have to add up, we'll call this extra right now to equal one or 100%. plus 18% plus x equals 100%. So then thinking about how That adds up to be .39. So you can subtract that .39 over 1 -39 is equal 2.61. And I would just stop right there. That there's a 61% chance that it's something other than GM or Toyota. Another way that you can do this is make a bend diagram and just think about, okay, there's no overlap. And then if you had the outside and just think about, well I need to have the outside that up to be 100-100% or one and then take away these two values to get .61. The correct answer. Mhm. Right
The board of directors for a major corporation cannot designed with that build its new assembly plant in Dallas. Chicago. If, in one of this city's chosen a channel, then what is the probability that a Dallas is chosen Be Memphis? He's no Children. See Tropical? It's Johnson. So is that a, uh, that diamonds? It's Johnson. Douglas is one of the cities. Ah, so what needs to be chosen? They all the citizens could equal chances so we can see. Ah, days one out off three. Now, the second question sees are about Memphis is not chosen. Ah, the that lamp is not chosen is equal to won. My last 20 is chosen which is do over and said close in essays. Oh, but Becca is chosen, since it's much, much off a symbol space er ages, eh? It is the now off ability about the victims that took. Baker is chosen because we only have place cities
It might make sense to look at a probability distribution chart on this one. To try to come up with what's going to happen. So we have ford I think the other company was Chrysler doesn't really matter. It's something, but then we just want other any other company. And so the bottom of this probability distribution is going to be your probability and you can leave it as percentages or you can leave as decimals. And since these two things do not overlap, there's no overlap between being a forward vehicle or being a Chrysler. But the whole thought process is the I'll just call this ex real quick is that those three situations, since there's no overlap, just need to add to equal one. And if it helps you write is 1.00. So all you have to do to sell for X is to subtract off the .15 And to subtract off the .12 or if you just do it in one swoop 10.15 plus 0.1 to 1.27. So therefore the X value, I'm just double checking with a calculator Is .73. So there's a 73% chance, whatever the context is of this question that it is not forward or Chrysler, it's some other company. Right,
In this question. Let us assume that we have to hold events. That is even A. And B. Event is that the vehicle is manufactured by the fault and the B. Is that the vehicle is manufactured by the company that is Nissan. Now we can see that well we'll deal. Uh he is given to us That is 0.12 probability of B. Is given to us. That is 0.02. And we can see that What a video of the intersection B is zero here because intersection B means both of them is not possible. Here means it is play. So will the intersection days. Okay. No you need to find up already here. That is the vehicle was manufactured by a neither company manufactured bye Neither company it means that it is not manufactured by the fall and the north manufactured later nation means no day and north we that is the ability a dash intersection beautician and you can see that It can be witnessed. 1- will be a union be That is 1- Trouble. D. A. Let's throw out your tv minus the probability of a intersection and After substituting your values we get 1 -1 0.12. Let's 0.02 minus zero. We can see that This provider one 0.14. And after simplifying it We can see that we get 0.86. So this is the um said of this question here. Thank you
