if i flip a coin 5 times, what is .... [math time]

[MiscMathematician]

if i flip a coin 5 times AND it is somehow known that exactly two heads have occurred

what is the probability that heads flips occurred together (right next to each other)?

[zeppl1n]

1 in 2 chance

[RyGla]

30%

There are 3 tails and 2 heads so you are basically asking the # of ways they can be together out of the total. Total number of ways is (5 c 2) and the total ways they can be together is (4 c 1) because there are 4 places to put the pair. So should be 4/10=0.4.

[DuracellBunny]

I'm tired, so I must be missing something obvious.

There are 2 ways the coin can land and you flip it 5 times, so that is 2^5=32 possible combinations

There are 4 ways it can be heads twice in a row

hhttt
thhtt
tthht
ttthh

So 4 out of 32, or 1 in 8 or 0.125

That seems far too easy, but I am tired.

No he's saying we already know we got 2 heads. It's part of the problem.

What about

hhhhh

hthhh
hhthh
hhhth
tthhh
htthh

+more ?

people are legit retarded itt, this will be your second math problem I have solved. 6 outcomes where heads occur together. 10 possible outcomes with two heads, the probability of heads occurring together ...6/10 or 3/5

here you go dum dum, number of outcomes where heads occur together ...right next to each other:

fuk on outta here, always knew you were a fukin fraud

You're listing 3 heads...

Read the question moron. And even if you were assuming 3 heads and 2 tails, you still forgot HHTTH, TTHHH, HTTHH, and HHTTH. Fukin retard.

[Paul Kreul]

Read the question moron.

correct, it's literally ONE of the outcomes IF YOU FLIP IT 5 TIMES..the question was 2 TOGETHER ..which would include 3 in a row being one of them

[WCline]

You literally forgot to list 4 outcomes, dipchit. 5 choose 2 is 10.

NA math, ladies and gentlemen. This is what the future of America looks like if Trump wins.

[Paul Kreul]

No I did not, you just don't understand math, reread my post and try again. You aren't as smart as you think you are..but I always knew that

[WCline]

Holy chit how are you THIS FUKIN RETARDED?

I LISTED ALL THE OUTCOMES FOR U IN POST #9. If you were Japanese, you'd have to commit seppuku rn because you have failed grandfather. DED FKN SRS.

YOU only got 4/10..I showed you 6/10, because you got it WRONG dum dum. how are you this fukin retarded? srsly..?

[WCline]

OMG how are you this stupid? It should be a crime. SRS. We need Chairman Mao 2.0 to rise and throw every American in a proper reeducation camp where they will be taught basic math. JFC

[Paul Kreul]

OMG how are you this stupid? It should be a crime. SRS.

I can't believe you are actually arguing about this LOL..do you really think you can discount 3 in a row..because you do realize in order to get 3 heads in a row ..YOU MUST FIRST GET 2 HEADS IN A ROW YOU ABSOLUTE FUHKING IDIOT

[sshheesshh]

Arguging over a question lmao

It says "exactly two heads have occurred"

[WCline]

He's so retarded.



Even if you assume he read the question as 2 tails and 3 heads, it is still wrong lmao. I'm not even sure how he read the question to get his answer. Like he just can't read or count. Literally retarded.

[Paul Kreul]

He's so retarded.

we'll see who is right if OP is honest.

2 heads "have occurred" when you get 3 last I checked lol

[WCline]

He said exactly 2 numbnuts. And you still forgot to list all outcomes then...way more if you are taking it out of all possible.

it said..2 heads occur together dum dum

[WCline]

we'll see who is right if OP is honest.

Honest like Trump lmao? 2+2=5 according to you or more appropriately 17 x 6 = 112.

[WCline]

it said..2 heads occur together dum dum

Yes which is why there are only 10 fkn possibilities. Exactly 2 heads occur. I listed them in post #9.

NA math fkn lmao.

incorrect. but we'll wait for OP.

[JackyChin]

I believe the answer is 4/10. Listed below are all possible outcomes with exactly 2 heads. Outcomes with the 2 heads occurring sequentially are bolded.

HHTTT

You are so hilariously dumb bro. I cannot imagine going through life like you.
