Question

if you roll a dice, what is the probability that a three will appear on top? explain.

Answer 1

When you toss a single cubical die, there are 6 possible outcomes, 1, 2, 3, 4, 5, or 6

Answer 2

There are six sides on a dice..you're looking for the probability for a three, which is one side.

Answer 3

The definition of probability is the number of favorable outcomes divided by the number of possible outcomes.

Answer 4

To roll a 3 is the favorable outcome,
There are 6 possible outcomes

Answer 5

well if there is a number of 5 then idk how to really make it even

Answer 6

P(3) = 1/6

Answer 7

^^^^^^^^^^^

Answer 8

The probability for it to land on any is 1/6..

Answer 9

1 because there is one favorable outcome

Answer 10

^^^

Meaning there is only one '3' on the dice.

Answer 11

You don't put 3/6 as the probability because there are not 3 ways to get a 3 in exactly one toss.

Answer 12

but there arent 6 numbers it ends at 5

Answer 13

Let me read the question again. I didn't see anything about a 5.
Now, if we're talking odds in favor of tossing a 3, then a 5 may be involved.

Answer 14

>>s it ends at 5 @mcnabkt What ends in 5? I don't get that.

Unless your answer ops are decimals.

Answer 15

yeah but it said on a dice which only goes from 1-5

Answer 16

Look at what you wrote: if you roll a dice, what is the probability that a three will appear on top? explain.

No mention of a 5-sided die and the default die is a cubical one of 6 faces.

Answer 17

I wrote this right off the bat >>>>>> When you toss a single cubical die, there are 6 possible outcomes, 1, 2, 3, 4, 5, or 6

Answer 18

but a dice doesnt have 6 numbers that is what im saying

Answer 19

Let's do this. You re-post the question EXACTLY as it appears in your book.

Answer 20

yeah and this is the question.

Answer 21

i thought a dice only had 5 sides?

Answer 22

So, you are not going to post the question as it appears in the book? I just want to be certain that we are both doing the same problem.

Answer 23

oh there is 6 sides

Answer 24

There exist five-faced die, but unless the problem specifies that, then the default assumption is the cubical die. A cube has six faces.

Answer 25

Those spots (dots, indentions) on one face of a die are called "pips."

Answer 26

okay

Answer 27

And, a cool tip. The number of dots on opposite faces sum to 7. Let me check to be sure but that is another cool fact.

Answer 28

\(\bf cool\)

Answer 29

Cubical Dice Image Below

Answer 30

A dice is a cube..all cubes have 6 sides..

Answer 31

@mcnabkt Is this explanation clear? Because if you are about to do a unit on probability, it is good that we clear the confusion, and I don't mind going through it again.

Answer 32

@greenlegodude57 I seriously like you reinforcement of the central concepts. Maybe we should work as a team.

Answer 33

Lol, I doubt I know nearly as much as you do.

Answer 34

all is being said, is how many faces a cube has, not anything of how i tell the probability of getting a certain number if i roll it.

Answer 35

The cubical die has 6 faces of equal area.

When you toss it, you can get a 1, 2, 3, 4, 5, or 6. Those numbers of dots are on the faces.

Answer 36

You are just as likely to get a 1 as you are a 2 as you are a 3 as you are a 4 as you are a 5 as you are a 6. That is called equally likely.

Answer 37

Toss the die. You want a "3" to come up. That means that the die lands with the upper face showing a 3.

Answer 38

Of the six possible outcomes of one toss of the cubical die, only one of them is a THREE.

Answer 39

That THREE is known in probabilty (study of chance) as the desired outcome or the favorable outcome as I call it.

Answer 40

The definition of probability is the fraction with numerator being the number of ways to get the favorable outcome divided by the number of possible outcomes.

Answer 41

There are 6 possible outcomes you could get on the one toss.

P(3) = (favorable outcomes)/(possible outcomes) = 1/6 .

Answer 42

@mcnabkt Bookmark this page or print out this thread so that after you rest up a bit, you can come back and read over it again.

Answer 43

There's a die tossing website somewhere on the Web. We should go there and throw a few.

Answer 44

Question?

Answer 45

nope. im done with this. i dont care

Answer 46

im having stress and no one can give me the answer then explain how i got it that is how i can understand it.

Answer 47

When I am torqued out, I cannot hear what anybody says. So, after you rest up and get some distance from this stuff, come back and we'll discuss it again. I'm going to try to find that site with the virtual die toss. I'm a visual learner so if you are, that would help.

Answer 48

yeah i am
