Question

Plz Help Me... I'll give medal..
Hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes? Explain..

Answer 1

I'm really not good at these..

Answer 2

Either method is equally likely. They both will produce a success at:

Probability = 1/6

The spin will give success at 1 out of 6

The dice roll will give success at 6 out of 36 -> 1 out of 6

They are equal as far as probability goes.

Answer 3

@nono266 is exactly right :)

Answer 4

Not quite.

Answer 5

You need to analyze each situation.

Answer 6

So Mathstudent55 what do you think?

Answer 7

oh
@mathstudent55 haha thanks @im_an_angel

Answer 8

First, what numbers are on the number cubes? Are there any matches? I still am amazed that some are offended by a reference to "Standard six-sided dice".

Answer 9

I'm really not good at Probability

Answer 10

If you spin a wheel with 6 equally likely results, then the probability of any of them is 1/6.

Answer 11

ok

Answer 12

No. I stand corrected.
You were right in the first place.
With the dice it's the same thing.
There are 36 total outcomes, and 6 of them are doubles, so the probability is indeed 6/36 = 1/6.

Answer 13

oh. ok

Answer 14

How should I explain it?

Answer 15

Are there eny awnsers

Answer 16

@Madi_Lee
Do you understand why with the wheel the probability is 1/6?

Answer 17

because of 1 out of 6?

Answer 18

Yes.

Answer 19

With the dice, you spin both dice.
There are 6 possible outcomes of the first die, and there are 6 possible outcomes of the second die.
The total number of outcomes is 6 * 6 = 36
(For each number you get in one die, you can get 6 numbers on the second one. Multiply them, and you get 36 total possible outcomes.)

Answer 20

Oh.. Ok

Answer 21

Now you need to see how many outcomes you are interested in.
The doubles spins are:
1,1; 2,2; 3,3; 4,4; 5,5; 6,6
As you can see, there are 6 possible doubles spins.
6 out of 36 is the same as 1 out of 6.

Answer 22

Oh. That's it?

Answer 23

Thank you

Answer 24

Yes. That's it.
