WILL MEDAL AND FAN how do u find the theoretical probability

@Luigi0210

OpenStudy (muscrat123):

@dani_00

OpenStudy (anonymous):

is that the whole question ??

OpenStudy (muscrat123):

no. it my personal question

OpenStudy (muscrat123):

to help solve a different ?

OpenStudy (muscrat123):

? = question

OpenStudy (anonymous):

no im just saying b/c thats non specific question. you dont find it, its a way of thinking that can relate to possible answers, get what im saying ?

OpenStudy (muscrat123):

sorta. but my school says this is how u find it and i dont understand \[\frac{ outcomes }{ number~of~possible~outcomes }\]

OpenStudy (anonymous):

its like weighing the options you have. idk how to explain it

OpenStudy (muscrat123):

yes!!!

OpenStudy (solomonzelman):

theoretical theory... lol...

OpenStudy (muscrat123):

thats exactly what im trying to do. hang on

OpenStudy (muscrat123):

OpenStudy (solomonzelman):

a coin can fall on either heads or tails.... (right?) So how many possible outsomes is there?

OpenStudy (anonymous):

2

OpenStudy (solomonzelman):

flipping the coin 100, omg, slap the teacher:O

OpenStudy (muscrat123):

i posted in comments what i have to submit

OpenStudy (muscrat123):

i have to flip TWO coins 100 times lol

OpenStudy (anonymous):

@Mehek14 :)

OpenStudy (muscrat123):

meow

OpenStudy (solomonzelman):

ok... experimental probability. Do you know what this term means?

OpenStudy (anonymous):

meow

OpenStudy (muscrat123):

the number of desired outcomes divided by the total # of trials. what is a desired outcome? and the total # of trials is what? in this case

OpenStudy (anonymous):

correct!

OpenStudy (solomonzelman):

the desired number of outcomes varies. the total number fo trials is 100

OpenStudy (solomonzelman):

the I mean number of desired outcomes.

OpenStudy (anonymous):

~meow~

OpenStudy (muscrat123):

but what is the desired # of outcomes in this case? IM SO CONFUSED :( !!!!!!!!!

OpenStudy (anonymous):

o wait no sorry

OpenStudy (anonymous):

i made a mistake sorry

OpenStudy (muscrat123):

@emma.elizabeth5683

OpenStudy (solomonzelman):

For a question: 2. What is the experimental probability that a coin toss results in two heads showing? desired outcome is when both coins lands on heads. the number of desired outcomes, is the number of times when both coins landed on heads. the total number of trials is the number times you have tossed (i.e. 100)

OpenStudy (anonymous):

Number of ways to succeed is one Number of possible outcomes is two Probability of getting heads is 1/2

OpenStudy (muscrat123):

so 32 / 100 for theoretical probability?

OpenStudy (solomonzelman):

number of desired outcomes / total number of trials is experimental probability

OpenStudy (muscrat123):

i meant 32 / 3

OpenStudy (muscrat123):

or 100 / 3?

OpenStudy (muscrat123):

im so confused

OpenStudy (anonymous):

what is your exact question given to you? c:

OpenStudy (solomonzelman):

so experimental probability (for question 2) is: (if you don't remember question 2, please read it) \(P=\rm (number~of~desired~outcomes)/(total~number~of~trials)\) \(P=\rm (32)/(100)\) \(P=\rm 0.32~~~~~or,~~8/25\)

OpenStudy (muscrat123):

i said 32/100 first!!!

OpenStudy (solomonzelman):

yes

OpenStudy (muscrat123):

its 32% for the theoretical probability, yes?

OpenStudy (solomonzelman):

and that is experimental probability for tossing both coins tails

OpenStudy (solomonzelman):

i confused the info 2 tails = 28 times 2 heads = 32 times

OpenStudy (muscrat123):

yes

OpenStudy (solomonzelman):

So, for question 2 it is 32% and for question 4 it is ? (do the same thing as we did for question 2)

OpenStudy (muscrat123):

wait...im still on ? #1

OpenStudy (muscrat123):

whats #1?

OpenStudy (solomonzelman):

u know what "theoretical probability" is?

OpenStudy (muscrat123):

no..that was my initial question

OpenStudy (muscrat123):

well sorta

OpenStudy (muscrat123):

@campbell_st

OpenStudy (muscrat123):

@Kash_TheSmartGuy

OpenStudy (campbell_st):

theoretical probability is what you expect to happen if you toss a coin P(head) = 1/2 and P(tail) = 1/2 its as simple as that

OpenStudy (solomonzelman):

theoretical probability. We don't look at any experiments that took place before. How many outcomes does a paticular operation (for ex. tossing a coin) can have? Now, what are the chances that it will behave in a particular way? The coin example: A coin can land on either heads or tails. What is a chance that coin lands on tails? It is 1/2.... So the theoretical probability of the coin landing on tails is 1/2.

OpenStudy (muscrat123):

so it is 33%?

OpenStudy (solomonzelman):

What is the chance that both coins will land on heads? The first coin has a 1/2 (or 50%) chance of landing on heads. The second coin has a 1/2 (or 50%) chance of landing on heads as well. But these are dependent events (since you want both of these to occur, so that both coins land on heads). This means that we multiply the probabilities/chances. ½ • ½ = ¼ (or 25%)

OpenStudy (solomonzelman):

Again, we aren't looking at how many times you have tossed the coins. The experiment is IRRELEVANT to any theoretical probability question that you have.

OpenStudy (muscrat123):

im still really confused and it needs to be done by 5

OpenStudy (muscrat123):

!!!

OpenStudy (muscrat123):

@Elsa213 @Skielerlucas04

OpenStudy (anonymous):

what the question

Elsa213 (elsa213):

@KyanTheDoodle is smart. Probably she can help. c:

OpenStudy (muscrat123):

i attached it in the comments. ill attach it again though

OpenStudy (muscrat123):

OpenStudy (muscrat123):

im having trouble determining what a desirable outcome is

OpenStudy (muscrat123):

@Vocaloid @Icedragon50

OpenStudy (muscrat123):

@Skielerlucas04 plz DONT LEAVE!!!

OpenStudy (muscrat123):

\(im~very~desperate!!!!!!!!!!!!!!!!!!!!!!!!!!!!!~\)

OpenStudy (anonymous):

idk how to do this, i have a LOT of work to do myself

OpenStudy (muscrat123):

do u know what a desirable outcome is?

OpenStudy (muscrat123):

@SolomonZelman can u help me more?

OpenStudy (muscrat123):

ughhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

OpenStudy (muscrat123):

@Kash_TheSmartGuy @KyanTheDoodle

OpenStudy (muscrat123):

@nincompoop

OpenStudy (muscrat123):

HELP!!!!!!!!!!!!!!!!!!!!!!!

OpenStudy (kash_thesmartguy):

Ok. calm down

OpenStudy (kash_thesmartguy):

Let's start with an example okay?

OpenStudy (kash_thesmartguy):

@muscrat123

OpenStudy (kash_thesmartguy):

Suppose you have a coin and your favor is to have tails. The theoretical probability would be: \[\frac{ Possible FovorableOutcomes }{ Number Of Outcomes }\]So that would result in a theoretical probability of \[\frac{ 1 }{ 2 }\]

OpenStudy (kash_thesmartguy):

@Jaynator495

OpenStudy (muscrat123):

nevermind. i figured it out on my own. and it would be 33.3% , not 50% bc there are 3 possible outcomes

OpenStudy (kash_thesmartguy):

I mentioned jay because in middle of testing.

OpenStudy (kyanthedoodle):

Woah! Woah woah! I don't know how to read!

OpenStudy (muscrat123):

? @KyanTheDoodle

OpenStudy (muscrat123):

u dont know how 2 read?
