Two coins one with HEAD IN BOTH SIDES and the other coin HEAD IN ONE SIDE AND TAIL IN THE OTHER SIDE is in a box,a coin is taken at random and FOUND HEAD IN ONE SIDE .what is the probability that THE OTHER SIDE IS HEAD?
please answer this questions guys :::::::
1.Two coins one with HEAD IN BOTH SIDES and the other coin HEAD IN ONE SIDE AND TAIL IN THE OTHER SIDE is in a box,a coin is taken at random and FOUND HEAD IN ONE SIDE .what is the probability that THE OTHER SIDE IS HEAD?
2.12 Blacksox and 12 Whitesox mixed in a box,a pair of sox is picked at a time,in which pick/ how many pick ,to get the right pair(black&black or white&white)?
3.16 litre can, 7 litre can,3 litre can,the customer has to be given 11 litres of milk using all the three cans only explain?
We hav three cans 16 litres, 7 litres, and 3 litres right...We wanna give 11 litres of milk using these 3 cans....Take first 7 litres can and add the milk to the container...now the contaier has 7 litres of milk..remaining is 4 litres...take 16 litres can and fill the can with the milk...using 3 litres can, take the milk from 16 litres can 4 times which means 12 litres of milk..therefore the left out milk in the 16 litres can is 4 litres..add tat milk to the container..now the total milk in the container is 11 litres

here a coin is taken at random and head is found for selecting a coin from 2 coins the probability is 1/2 and a head is already found in 1 side and the probability of getting tail on other side is 1st coin-0 2nd coin -1 so total probability is 1/2(1+0)=1/2

picking up sox here 12 black and 12 white are there soo we have to make a black and white pair so 1st selectting black from 12 black sox 12c1 2nd selecting white from 12 white sox 12c1 cumulation total successful pickups-12ci*12c1=144

1) The probability of selecting one coin is 1/2(which is already completed) now.. The probability of having head on other side is (1/2) since only one coin has head. Therefore the prob. that head on other side is 1/2(second value from above explanation)
2) selecting 2 black ones is (no of ways) : 12c2
selecting 2 white ones is :12c2
therefore, selecting a pair of particular color is 12c2+12c2 = 66+66 = 132
selecting 1 black & one white is : 12c1*12c1 == 144
Lets assume worst case (which is required)
since 144 is greater than 132.
the first pick will be black & white, 2nd pick is also black & white ,3rd will be black or white, no of picks required : 3
3) use 7 lt can and pour milk in 16lt can, now take milk in 7lt can, take 3lt from that 7lt can, 7lt can will have 4 lts in it, pour that 4 lt in 16lt can, it has 7(previous)+4(later) in it...

i guess we have to use the formula ncx p^x q^(n-x) where n =2 which is the no of coins 2c1(.5)(.5) so probability of gettin head on both sides is 0.5

Answer is 3/8. probability to come head on face is 3/4. but the question is what is the probability that other side is head? since there are 2 coins, in which 1 had both side head and 2nd have one head n one tell. so the probability for other side to come head is 3/4 * 1/2 = 3/8 if i am wrong, please correct me!!!!
