mewho is doing 62 tomorrow ?
Good Luck!
did you get answer to these ?Hey there can u help me with these questions please. I shall be very grateful. If u can include some explanations to refresh a bit my memory, would be nice ^^
I've included the expected answer in red.
Yeah. someone had pm me the answers, months ago ^^did you get answer to these ?
ok draw a tree diagram. for first branch you do 0 and not zero. secod branch p>=4 and p<4. so you get 0.2*0.4 as the required branch which is the probability.Cool thanks!
I have posted a doubt above. can u help me in dat?
Sorry i don't get it. Where does that 0.2 come from?ok draw a tree diagram. for first branch you do 0 and not zero. secod branch p>=4 and p<4. so you get 0.2*0.4 as the required branch which is the probability.
for part 2 you say a=winning the first time which is 0.2. then do a g.p where 2nd term is 0.08,a is 0.2 to give r as 0.2
so p=0.4(0.2^n-1)
p(4)+p(5)+p(6) = 0.16+0.16+0.08=0.4 !!!add probabilites for 4,5,6
Gosh! yeah, how stupid of me (*facepalm*)! Yeah i got it. thanks buddy!sorry my bad, i thought u meant p>=4 the 0.2 comes from the prob distribution table,at p=0. u know how to mak it right?
Its because (BBGG) can be arranged in 6 different waysbabycry Can I annoy you one last time? See my doubt on top of this page. please. ^^
i totally agree with u the 2nd method is betterIts because (BBGG) can be arranged in 6 different ways
They are:
GGBB GBBG BBGG BGGB BGBG GBGB
Or 4!/(2!2!)
Or 4C2 ways as out of 4 people u choose 2.
When you get the probability for one combination, multiply by six to get total probability as it can occer 6 different ways. This is because they are mutually exclusive
And insted of adding 6 times, its easier to multiply by 6
Personally its easier to do it by the second method as you skip alot of calculations
can you give the answer to question 5 part 2 ? thanks in advanceHelp needed with:
