Best ResponseYou've already chosen the best response.0In this experiment, you will be using two coins as a simulation for a realworld compound event. 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. 3. Flip both coins 50 times and record your data in a table like the one below. Result Frequency Heads, Heads Heads, Tails Tails, Heads Tails, Tails Total 50 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?

Best ResponseYou've already chosen the best response.0ok now what? @Vocaloid

Best ResponseYou've already chosen the best response.1ok, keep them with you, we're going to need them pretty soon let's start with #1: the theoretical probability that the family will have two dogs or two cats first, the problem tells us that the probability of getting a dog and a cat are equally likely, so probability of a dog = 1/2 probability of a cat = 1/2 so, probability of two dogs = (probability of a dog)*(probability of a dog) = ?

Best ResponseYou've already chosen the best response.1right probability of two cats = (probability of a cat)*(probability of a cat) = ?

Best ResponseYou've already chosen the best response.1right, now we add the together to get our answer for #1: 0.25 + 0.25 = ?

Best ResponseYou've already chosen the best response.1right, let's move on to #2

Best ResponseYou've already chosen the best response.1we're going to use a coin to represent each pet. the probability of getting heads on a coin is 1/2 and tails is also 1/2, just like dog = 1/2 and cat = 1/2 so, we'll flip the coins one by one. a heads represents a dog and a tails represents a cat. so, as an example, if we flip heads on the first coin and tails on the second, that represents the family getting a dog and then a cat

Best ResponseYou've already chosen the best response.1that should be a sufficient answer for 2, just don't copy my words directly, ok?

Best ResponseYou've already chosen the best response.0ok i wont copy.. i put it in my words, dont worry.

Best ResponseYou've already chosen the best response.1#3 is asking you to do the simulation I just described take both coins, and flip them one at a time. now, take a look at each row of the table: Heads, Heads means the first coin is heads and the second coins is heads Heads, Tails means the first coin is heads and the second coin is tails Tails, Heads, means the first coin is tails and the second coin is heads Tails, Tails, means the first coin is tails and the second coin is tails

Best ResponseYou've already chosen the best response.1so, take your two coins. flip the first one, flip the second one, and tell me what you get for each one

Best ResponseYou've already chosen the best response.0i got heads and heads

Vocaloid

Best ResponseYou've already chosen the best response.1right, so we put a tally mark in the first row, "Heads, Heads". now do the same thing 49 more times and fill out the table

Vocaloid

Best ResponseYou've already chosen the best response.1it wants you to flip both coins 50 times

Vocaloid

Best ResponseYou've already chosen the best response.1so, we just flipped both coins once, and now we do the same thing 49 more times

Best ResponseYou've already chosen the best response.0but what do i put for frequency

Vocaloid
 one year ago
Best ResponseYou've already chosen the best response.1frequency is the number of times you get for each of the 4 outcomes

Vocaloid

Best ResponseYou've already chosen the best response.1so keep flipping the coins and keep track of how many times each outcome happens

Best ResponseYou've already chosen the best response.1make sure to stop at 50

Best ResponseYou've already chosen the best response.1that adds up to 56 not 50

Best ResponseYou've already chosen the best response.0oh whoops.. hold on let me fix it

Vocaloid

Best ResponseYou've already chosen the best response.1much better, now let's move on to #4

Vocaloid

Best ResponseYou've already chosen the best response.1take a look at your table, and add together: Heads,Heads + Tails,Tails

Vocaloid

Best ResponseYou've already chosen the best response.1now divide that by 50 and there's our answer

Best ResponseYou've already chosen the best response.1let's move to #5: probability of 3 cats or 3 dogs going back to what we said earlier... probability of cat = 1/2 probability of dog = 1/2 so probability of three dogs = (probability of dog)*(probability of dog)*(probability of dog) = ?

Vocaloid

Best ResponseYou've already chosen the best response.1right probability of 3 cats = (probability of cat)*(probability of cat)*(probability of cat) = ?

Best ResponseYou've already chosen the best response.1now add them together 0.125 + 0.125 = ?

Best ResponseYou've already chosen the best response.1right, that's our answer for #5

Best ResponseYou've already chosen the best response.1for 6, all we need to do is use 3 coins instead of 2 coins, since we want 3 pets

Vocaloid

Best ResponseYou've already chosen the best response.1"How could you change the simulation to generate data for three pets?" our simulation used 2 coins and made data for 2 pets, so if we wanted 3 pets, we would use 3 coins instead of 2....
