There are n urns each continuous (n+1) balls such that the ithurn contains 'I' white balls and (n+1-i) red balls. Let `u_(1)` be the event of selecting ith urn, i=1,2,3……..n and W denotes the event of getting a white balls.
If `P(u_(i))=c`, where c is a constant, then `P(u_(n)//W)` is equal to

A

`(2)/(n+1)`

B

`(1)/(n+1)`

C

`(n)/(n+1)`

D

`(1)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
`P(u_(n))/(W)=((n)/(n+1))/((Sigmai)/(n+1))=(2)/(n+1)`

Each of the n urns contains 4 white and 6 black balls. The (n+1) th urn contains 5 white and 5 black balls. One of the n+1 urns is chosen at random and two balls are drawn from it without replacement. Both the balls turn out to be black. If the probability that the (n+1) th urn was chosen to draw the balls is 1/16, then find the value of n .

Consider three boxes, each containing 10 balls labelled 1, 2, …, 10. Suppose one ball is randomly drawn from each of the boxes denoted by n_(i) , the label of the ball drawn from the i^(th) box, (I = 1, 2, 3). Then, the number of ways in which the balls can be chosen such that n_(1) lt n_(2) lt n_(3) is

There are two urns Aa n dB . Urn A contains 5 red, 3 blue and 2 white balls, urn B contains 4 red, 3 blue, and 3 white balls. An urn is chosen at random and a ball is drawn. Probability that ball drawn is red is a. 9//10 b. 1//2 c. 11//20 d. 9//20

A box B_(1) contains 1 white ball, 3 red balls, and 2 black balls. An- other box B_(2) contains 2 white balls, 3 red balls and 4 black balls. A third box B_(3) contains 3 white balls, 4 red balls, and 5 black balls. If 2 balls are drawn (without replecement) from a randomly selected box and one of the balls is white and the other ball is red the probability that these 2 balls are drawn from box B_(2) is
