Let S be the sample space.
Here n(S)= 23 = 8
Let E be the event of getting atmost two heads. Then,
n(E) = {(H,T,T), (T,H,T), (T,T,H), (H,H,T), (T,H,H), (H,T,H)}
Required probability = n(E)/n(S) = 6/8 = 3/4.

Let Althaf lent Rs. A at 14% per year.
Hence, Money lent at 12% = (1500-A);
Given, total interest = Rs. 186.
{(A x 14x 1)/100} + {[(1500-A) x 12 x 1/100]} = 186;
14A/100 + (18000 -12A)/100 = 186;
14A + 18000 - 12A = 186x100;
2A = 18600-18000;
A = 600/2 = Rs. 300.
Hence, money lent at 12% = 1500-300 = Rs. 1200.

(300 – 101)/11 = 199/11 = 18 1/11

Accounting is the systematic and comprehensive recording of financial transactions pertaining to a business. 

Accounting also refers to the process of summarizing, analyzing and reporting these transactions to oversight agencies, regulators and tax collection entities. 

ddNTPs - Dideoxynucleotides and abbreviated as ddNTPs.

They are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing.

They have a hydrogen at the 3’ carbon of the ribose sugar.

Chloroform, CHCl3 is easily oxidised to the highly poisonous gas known as phosgene or carbonyl chloride COCl2. Hence if it is used as anaesthetic it should be kept free from sunlight and air.
