Question

Simulating a problem, please help!
I am asked to simulate the probability of statements like "collect all 8 dinosaurs" or "one in each specially marked cereal box." I spun a wheel 3 times, and my answers were these for the 1st, 2nd, and 3rd spin:
Tyrannosaurus rex: 2, 1, 4
Velociraptor: 3, 1, 1
Apatosaurus: 1, 1, 5
Stegosaurus 3, 2, 1
Pterodactyl: 2, 2, 2
Allosaurus: 3, 3, 1
Gigantosaurus: 1, 2, 1
Triceratops: 2, 3, 2

I have no idea how to solve this...

Answer 1

The first question I have to answer is: What was the theoretical probability of collecting a specific dinosaur, such as a Velociraptor, in a single purchase?

Answer 2

what do those numbers represent when u spin

Answer 3

The spinner is to determine how many boxes of cereal I might need to purchase to collect all eight dinosaurs.

Answer 4

ok

Answer 5

Tyrannosaurus rex: 2, 1, 4 -->calculate the avg of the boxes u need to purchase
Velociraptor: 3, 1, 1
Apatosaurus: 1, 1, 5
Stegosaurus 3, 2, 1
Pterodactyl: 2, 2, 2
Allosaurus: 3, 3, 1
Gigantosaurus: 1, 2, 1
Triceratops: 2, 3, 2

Answer 6

Do I add, divide, or multiply?

Answer 7

tell me this
say you are 12 years old and your brother is 10 years old
what is the average age between you 2

Answer 8

2 years

Answer 9

oh, u dont know what average means?

Answer 10

lets say you write 2 tests
you get 50% on one and you get 100% on the other
what is your average right now?

Answer 11

Oh, ok, my average then is 75%, correct? Sorry, I was a bit confused

Answer 12

yes

Answer 13

so ur telling me each time you spin
that tells you how many boxes you needed to get that dionsaur

Answer 14

so your needed 2 boxes on the first try to get that dinosaur and 1 boxes the next time to get that dinosaur and 4 boxes the 3rd time to get that dinosaur, so on average how often are you getting that dinosaur

Answer 15

Ah, 2.33?

Answer 16

yeah ok

Answer 17

that is how the spinnner is right

Answer 18

can you tell me your question as it is

Answer 19

"The spinner is to determine how many boxes of cereal I might need to purchase to collect all eight dinosaurs."
are you sure they* dont mean those 3 spins together determine how many boxes you need to get that dinosaur?

Answer 20

"For this exercise, the probabilities refer to the probability of getting any one dinosaur when making any one purchase. You do not need to determine the probability of the compound event of getting all eight of the dinosaurs."

Answer 21

ok

Answer 22

i think u those 3 spins are saying how many boxes in total u need to get that 1 dinosaur so just add them

Answer 23

i dont think theyll make it so u have to calculate avg for everyone.. thats a little be too tedious and the probability values dont make sense

Answer 24

Tyrannosaurus rex: 2, 1, 4 =7
Velociraptor: 3, 1, 1=5
Apatosaurus: 1, 1, 5=7
Stegosaurus 3, 2, 1=6
Pterodactyl: 2, 2, 2=6
Allosaurus: 3, 3, 1=7
Gigantosaurus: 1, 2, 1=4
Triceratops: 2, 3, 2=7

Answer 25

Tyrannosaurus rex: 2, 1, 4 =7 ; Prob = 1/7
Velociraptor: 3, 1, 1=5; prob = 1/5
Apatosaurus: 1, 1, 5=7; p=1/7
Stegosaurus 3, 2, 1=6; p= 1/6
Pterodactyl: 2, 2, 2=6 p = 1/6
Allosaurus: 3, 3, 1=7 p = 1/7
Gigantosaurus: 1, 2, 1=4 p = 1/4
Triceratops: 2, 3, 2=7 p= 1/7

Answer 26

Ahhh, now I think get it, thanks a lot!
