Given that the drawn ball from U2 is white, the probability that head appeared on the coin

A

`(17)/(23)`

B

`(11)/(23)`

C

`(15)/(23)`

D

`(12)/(23)`

Text Solution

Verified by Experts

The correct Answer is:
D
`P("Head appeared/white from" U_(2))`
`=P(H)*({(""^(3)C_(1))/(""^(5)C_(1))xx(""^(2)C_(1))/(""^(2)C_(1))+(""^(2)C_(1))/(""^(5)C_(1))xx(""^(1)C_(1))/(""^(2)C_(1))})/(23//30)`
`=(1)/(2)({(3)/(5)+1+(2)/(5)xx(1)/(2)})/(20//30)`
`(12)/(23)`

Let U_1 and U_2 be two urns such that U_1 contains 3 white and 2 red balls, and U_2 contains only 1 white ball. A fair coin is tossed. If head appears then 1 ball is drawn at random from U_1 and put into U_2. However, if tail appears then 2 balls are drawn from U_1 and put into U_2. Now, 1 ball is drawn at random from U_2 Given that the drawn ball from U_2 is white, the probability that head appeared on the coin is

A fair coin is tossed repeatedly. If head and tail appear alternatively on first 7 tosses, then the probability that head appears on the eighth toss is
