Entropy is a measure of disorder . It will be maximum in gases followed by liquids and least in solids.

Hence, here the gas is only hydrogen and it has the highest entropy.

Possible outcomes = (RY, YP, PR)

2C1 4C1 + 4C1 6C1 + 6C1 2C1

Required probability = (2C1 4C1 + 4C1 6C1 + 6C1 2C1)/(12C2)

= 8 + 24 + 12/66

= 44/66

= 2/3.

1) Man's wife. = 1
2) Man's 4 son's wives. = 4
3) Man's daughter. = 1
4) 4 son's has each one daughter. = 4
Therefore, total number of female members in the family = 1+4+1+4 = 10.

As from the given conditions;
Order is

Here the student standing in the middle is 'Q'.

Normally, urine contains water and wastes, such as urea, uric acid, creatinine, and some ions. However, some of these substances may be abnormally elevated, which usually indicates that something is wrong with the body.

The following are some of the abnormal constituents of urine::

We can select atleast one item from 6 different items = 26-1  

Similarly we can select atleast one item from other set of 6 different items in 26-1 ways. 

Required number of ways = (26-1)26-1 = 26-12 = 3969

(100-x)%  of 88% of 8400 = 6896

=> 100-x10088100x8400 = 6896

=> x = 6.709%

A Perch is a fresh water fish. Similarly, a cod is a salt water fish.

Hence, Perch : Fresh Water :: Cod : Salt water.
