difference between nominal account and representative account​

The second reason ochem is so difficult to learn is that it's a memorization nightmare. Not only are there more than 15 million organic compounds, but there are different rules governing the reactions and properties of each of these compounds. The trickiest part is how often the rules change.

Bhaiya mujha bhi organic chem hard lagta ha samj nahi Ata ki kare kya hota ha kbhi ya to kabhi wo :)

My undergraduate degree is in Industrial Chemistry. I graduated with honors and found all of my major classes pretty easy — except for Organic Chemistry. I am extremely good at memorization and I am probably best than most in problem solving, specially if you could use math to solve the problem, but pretty much any kind of problem solving I am great at. Still, Organic Chemistry wasn’t as intuitive as all of the other courses. That is one reason I wanted to get a PhD in Organic Chemistry — I thought there must be some kind of trick to it to make it easy and I needed to find out what it was. I eventually found out what my problem was, at my subconscious level I could not believe my own inability to predict the outcome of organic reactions with logic and mathematical modeling alone. I was trying to find specific patterns and numeric logic to Organic Chemistry and encase the outcome of reactions to my past experience, but some reactions simply defied my internal logic and knowledge. I actually needed to memorize the way that bonds had behaved in the past and use only that, even if that information would go against my own logic. Once I trained my brain to stop applying my own logic to try to solve the problems, and instead use only the patterns I had memorized, I was able to master the courses, but I have to admit — my brain complained and squealed because that is not in my nature. But even after mastering what they teach you in college, the real issue is that organic reactions don’t always go as you would expect, as a matter of fact, scientists still can’t figure out the absolute logic in organic chemistry, which is why is so hard to create a good computational simulation software for organic reactions that would be reliable and that is why we always have to try the our theories in the lab, sometimes they just defy our expectations. Think about it, if organic chemistry were easy, we could easily program computers to tell us exactly what you would get with any kind of established parameters and we wouldn’t need to do things in the lab. There have been many advances in biological computing and in many kind of engineering, but there is still a lot to do in organic chemistry. In a sense, organic chemistry is similar to human behavior, you can theorize the outcome, usually based on past behavior, but many times it just surprises us.

Answer:

If the probability that a problem will be solved by three people is 1/2, 1/3 and 1/6, then what is the probability that the problem will be solved?

Probability of A solving the problem = P(A) = 1/2

Probability of B solving the problem = P(B) = 1/3

Probability of C solving the problem = P(C) = 1/6

Problem will be solved when i) either one of A, B, C solve the problem, ii) two of A, B, C solve the problem, OR iii) all of A, B, C solve the problem

Problem will not be solved when - all of A, B, C are not able to solve the problem

Probability of A not solving the problem = P(A) = 1/2

Probability of B not solving the problem = P(B) = 2/3

Probability of C not solving the problem = P(C) = 5/6

Probability of problem not being solved = A, B, C not solving the problem simultanously = P(A)*P(B)*P(C) = (1/2)*(2/3)*(5/6)

= 5/18

Probability of problem being solved = 1 - probability of problem not being solved

= 1 - (5/18) = 13/18

Answer:

The probability of completing the task on time is 5/6

Step-by-step explanation:

Given the probabilities of completion of a task by the employees

A, P(A) = 2/3

B, P(B) = 1/4

C, P(C) = 1/5

D, P(D) = 1/6

Now if we compute the probabilities of not completing a task we get

P'(A) = 1/3

P'(B)  = 3/4

P'(C) = 4/5

P'(D) = 5/6

The task will not be completed if none of them is complete the task on time.

P(not completing the task) = 1/3x3/4x4/5x5/6 = 1/6

Now the probability of completing the task is 1-1/6 = 5/6

Step-by-step explanation:

Given The number of primes in positive integers less than 50 is

• We have a prime number is a number which is divisible by one and itself.
• So we need to find the number of positive integers that are prime numbers and which are less than 50.
• Now we have the numbers as
• 1,2, 3, 5,7,11,13,17,19,23,29,31,37,41,43,47.
• So the total number of primes less than 50 is 16.
