WILL MEDAL AND FAN!!!!!!!!!!!!!!! Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats. 1. What is the theoretical probability that the family has two dogs or two cats? 2. Describe how to use two coins to simulate which two pets the family has. @dan815 @uybuyvf @Hero @ganeshie8 @LynFran @Mehek14 @nandabo_ @pooja195 @teagirl7630 @imqwerty @zepdrix

this is what i put for #2: 2. Describe how to use two coins to simulate which two pets the family has. I can use two coins to simulate which two pets the family has by letting heads represent how many dogs there are and letting tails represent how many cats there are.

okay so Pet 1 is either a Dog or a Cat and Pet 2 is either a Dog or a cat you need to see what prob is it where they are both dogs or both cats

  • muscrat123
i mean 1/2 ?
dan815
  • dan815
yes
dan815
  • dan815
now with 2 coins instead of , dog and cat, u have heads and tails
muscrat123
  • muscrat123
so the theoretical probability of there being 2 cats/2 dogs is 50%
muscrat123
  • muscrat123
which is #1 s answer, yes?

"now with 2 coins instead of , dog and cat, u have heads and tails" so what i put for #2?
dan815
  • dan815
you repeat the same thing with heads and tails as dogs and cats

i put this for #2 2. Describe how to use two coins to simulate which two pets the family has. I can use two coins to simulate which two pets the family has by letting heads represent how many dogs there are and letting tails represent how many cats there are.
dan815
  • dan815
okay, go on, u have to talk about what u do with those heads and tails
muscrat123
  • muscrat123
^^^ hang on

  • muscrat123
here, ill just post the whole thing
muscrat123

  • dan815
oh muscrat what u can do is, basically flip coins a bunch of times and see the probability u are getting 2 heads and 2 tails
dan815
  • dan815
and over time it will be half the time for every 2 flips
dan815
  • dan815
and u can talk about why this is happening by drawing a tree diagram, or using some other method to show why the theoretical prob is 50%
muscrat123
  • muscrat123
what does that mean? how can i put that into an answer for something?

what lesson is this?

7.03 on FLVS
dan815
  • dan815
well you see in part 3) they are flipping coins 50 times and recording the data, they are trying to show you that the experimental probability will start to follow the theoretical prob
muscrat123
  • muscrat123
the chart is what i did....
muscrat123
  • muscrat123
@dreamio why?
anonymous
  • anonymous
cause i did the same lesson

did u get a 100?
anonymous

no i got a 15/20 haha but i know what i got right

haha ok but i dont have number 5
muscrat123
  • muscrat123
ok
muscrat123
  • muscrat123
im sure ill b able to figure it out...probably
anonymous
  • anonymous
its from my experiment so dont forget to fill it in with your info
muscrat123
  • muscrat123
is number 5 33% or did u put that and it was wrong? numbers 4-6: 4. Based on your data, what is the experimental probability that the family has two dogs or two cats? 5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats? 6. How could you change the simulation to generate data for three pets?
anonymous
  • anonymous
i didnt put that for 5 so i dont know sorry
muscrat123
  • muscrat123
what did u pu tfor other questions?
anonymous
  • anonymous
it wont let me copy and paste

  • anonymous
give me a minute im sorry
muscrat123
  • muscrat123
ok its ok

1. What is the theoretical probability that the family has two dogs or two cats? 1/2 2. Describe how to use two coins to simulate which two pets the family has. For the stimulation heads will be cat and tails will be dog, so if you get something like two heads that will mean two cats . 4. Based on your data, what is the experimental probability that the family has two dogs or two cats? 27/50 or 54%. 6. How could you change the simulation to generate data for three pets? I would change the amount of coins to three.

got it?
muscrat123
  • muscrat123
yea, can u get ur table on here? i have trouble with experimental and theoretical probability
anonymous
  • anonymous
Result Frequency Heads, Heads 14 Heads, Tails 13 Tails, Heads 12 Tails, Tails 13 Total 50
anonymous

that?
muscrat123
  • muscrat123
yes!
anonymous
  • anonymous
haha well everyone's is different because its experimental but yeah thats what i got
muscrat123
  • muscrat123
i got it now, do u think u can check over my answers b4 i submit it?
