C and D are two events such that P(C) = 0.2, P(D) = 0.6 and P(C|D) = 0.3. Find P(D|C), P(C’ ∩ D’) & P(C’ ∩ D)

Here we use the formula for conditional probability:P(C|D)xP(D)=(𝑃(C∩D))= 0.3x0.6=0.18Note: 𝑃(C∩D)=𝑃(D∩C)=0.18Hence P(D|C)=𝑃(D∩C)/P(C) = 0.18/0.2 = 0.9P(C'∩D') = P(C'|D')xP(D')P(C'|D) = 0.7P(D')=0.4P(C')=...

Solve the simultaneous equations 3x + 2y = -7 and x=4y+21

Substitute in the second equation into the first to eliminate x from the first equation. Solve for y which should, when solved (shown below), equal -5. Sub -5 back into either equation in the place of y t...

Why do you think species have evolved to use ATP rather than GTP?

First of all, the difference between them is that ATP contains the base adenosine and GTP contains guanosine. One of the significant differences between these molecules is that guanosine contains an extra...

Why does iodine have a higher boiling point than chlorine?

Iodine is a larger molecule, with more electrons, than chlorine. Therefore Iodine has stronger intermolecular forces than chlorine, which require more energy to break. This results in Iodine having a high...

What is the role of oxygen in the electron transport chain, and why is it so essential?

Oxygen acts as the final electron acceptor in the electron transfer chain, resulting in the formation of H2O. This is essential because without it, the electron transfer chain cannot function r...
