Is mating within a population random?
Yes, mating within a population is random. However, it is possible for non random mating to occur within a population.
What is the mathematical definition of random?
There are a number of definitions. In mathematics, it depends on the context that the word is used. One definition is for a "random event" where all outcomes are equally likely to occur. A random selection of lottery numbers means that in the long run, no one number is likely to occur more than another one. Random events are typically considered independent random events, in that one event can not affect the outcome of another one. A "random variable" means that the probability of any value occurring corresponds to a given probability distribution function. There is a common use of random, which means to act without a plan.

What is meant by bimodal distribution?
You are likely familiar with the probability density function of the normal distribution--that is, the bell-shaped curve.A bimodal distribution is one whose probability density function has two 'humps' or maxima. In other words, values of the random variable are more likely to occur around where those two maxima occur than elsewhere, in the same way that values of a normally distributed random variable are more likely to occur around its maximum.

Compensating and biased errors in statistics?
These errors occur due to chance. These errors tend to cancel to each other in long run. These errors are random. They are not the results of any prejudice or bais.
