Answer / sai kiran kumar
sry guys ans is 14/19 vch is greater den 1/2...
shifting is allowed therefore shift 9red balls to green bag
which makes it 1 nd 19 (red balls in each bag)
so probability = (1/2)*1+1/2(9/19)=14/19 :) :) :)

Answer / m4a1_cs
how this can be???
the probability for selecting red box is 1/2 but randomly if
we select green box, the probability will be 0.
so, total probability for this case is 0.5.
now consider the other case, 9 red balls are transferred to
green ball box. now total balls in that box will be 19.
total probability = probability to select 1st box +
probability to select 2nd box
= (1/2)*(1C1/1C1)+(1/2)*(9C1/19C1)
= (1/2)*(1+9/19)
= (1/2)*(28/19)
= 14/19

Answer / somasundarraj
You are allowed to move the balls between the boxes so that
There are two boxes, one containing 10 red balls and the
other containing 10 green balls.when you choose a box at
random and a ball at random from the chosen box, the
probability of getting a red ball is maximized. This maximum
probability is
When ever you think your selected box have maximum no of
probability that means p(ball taken) maximum is 1.
but you must first select the box from two boxes this p(box
choosen) is always constant=1/2.
Finally the answer is maximum p(getting a red ball)=1/2

Answer / srinivas
First to select a box the probability is ½.
Initially if I select a ball from the box containing red balls the probability is 1.
After shifting the balls the maximum balls shifted is 10.
Then the probability of selecting a red ball from 20 is ½
Therefore the answer is ½*1+1/2*1/2 =3/4

1.) In the coming state elections, Bharat Mata Party (BMP) will contest for 77 assembly seats. As BMP's majority vote bank is distributed amongst three communities viz. A, B and C, it will give election tickets only to those workers who belong to these communities. The workers of communities B and C are split into factions. Every faction of community B has 15 workers and that of community C has 25 workers. There were no factions among the workers belonging to community A. If BMP gives a ticket to a worker, it must give tickets to every other worker belonging to the same faction. BMP distinguishes between any two workers only on the basis of their communities. In how many ways can BMP distribute its election tickets giving at least one ticket to each community?

Tis known in refined company, that choosing K things out of N can be done in ways as many as choosing N minus K from N: I pick K, you the remaining. This simply states the binomial coefficient identity . Find though a cooler bijection, where you show a knack uncanny, of making your choices contain all K of mine.For pedantry let K be no more than half N.
