P(at least 2 boys|1boy)

how to solve this P(at least 2 boys|1boy) ?

you can click edit and put it in the blue part

thnks for suggestion

is this like bayes therem

no just conditional probability
Bayes is a little different

P(at least 2 boys)/P(at least one boy)=(1/3+1/3)/(3/3)

not quite...
P(At least 2 boys) = P(2 boys) + P(3 boys)
P(at least 1 boy) = 1-P(no boys)

=(1/3+1/3)/(1-0/3) =?

final answer=(2/3)/(1/8)=1/12

|dw:1444505252205:dw|

the area of the smallest circle divded by the bigger circle

P(at least 2 boys)/P(at least one boy)=(1/2)/(1/8)=1/4 , is it

|dw:1444505457548:dw|

|dw:1444505579498:dw|

but the answer given inn book is \(\large \dfrac34\)

i m very confused

i prolly messed up somewhere, trying a slightly weird method

pgpilots way is more intuitive

b gg
b gb
b bg
b bb
3 out of 4 in the sample space have at least 2 bs, given 1b

oh amistres way makes sense xD

however im not too sure if thats all there is to it, like in his scneario the first one is always b

i m dipresed

lmao

why

which answer is correct

we can see :)

with a program

hey its 4/7 ya

oh ok 4/7

i hope ur program is correct

like is it 3 kids +1 boy that is given
or is it saying 3 kids where 1 of those 3 is a boy
?

what is the difference between bbg and bgb

both of those say 2 boys and one girl

the sample space is preserved, in my mind

i tend to do card probabilities with P instead of C as well ... dont know why

how do we know age matters?

thats not how it works i thnk

u are only considering b first then

so its not exactly 3/4 its actually a bit less

you can manually check its usually less than 3/4 and around 4/7

this is what @amistre64 was saying earlier I believe
to far up to scroll

I think I agree with @amistre64 now

the book answer is wrong

but isn't your answer suggesting B doesn't have to come first?

B doesnt ahve to come first though

they just want B anywhere

Then how did you all those extra possibility

watcha mean

Like if B has to come first then you only have:
the possibilities I just suggested

yeah that is true

but B doesnt haev to come first so we gotta consider everything

oh I thought you said B had to come first

the answer suggest the book doesn't care about age
your answer suggest the book cares about age

I think

i dunno lemme think lol

i was just think about this picture

|dw:1444514572870:dw|

yeah i did consider the different permutations
BGB
BBG
GBB

and you can omit the GGG from the list above

oops nope I'm confused again

because BGB is the same as BBG

err...

i think since the kids are already borned ... that age is not relevant

kinddd offfff

is this a correct interpretation? lol ... in my case i never know

lol kind of i mean whats stopping us from just looking at everything

thats kind of the way i approached it

i removed the ones where it was all 3 girls i mean

Do we agree that there is a higher probability of there being 2 boys than there is of being 3 boys?

yes

right

probabilities amistre gave are not all equal... if they were, then it would be 3/4.
