It depends largely on the area of Biology that one is talking about, however just about every aspect of biology hinges on some aspect of probability.

In Genetics for example, the probability of random assortment of genes can tell how close two genes are on the chromosome. Likewise, probability of different parental genotypes mating will give an idea of what the f1 generation will look like. Also, if one looks at the probability of random mutation of a single point, one can estimate the conversion of one genotype to another (assuming the point mutation is not lethal and the protein product cannot form correctly).

In other words, it is essential in a variety of ways in Biology.

How useful probability in statistics?

Statistics is based on the theoretical foundation of probability.


If there are 45 students in a biology class and 23 are girls what is the probability that a student chosen at random will be a boy?

Probability that a girl is chosen = 23/45 = .511 So, the probability that a boy is chosen = 1 - .511 = .489


Where is probability used in the real world?

Probability is used everywhere: Betting odds. Medical odds, (chance of survival or chance of side effect happening). Anywhere we calculate risks (insurances calculate premiums based on probability). Communication Networks


How do you do a probability?

Number of useful outcomes over number of possible outcomes and simplify it if you can. Imagine you want an even number and you roll a die. There are 6 possible outcomes and three of them are useful outcomes (outcomes we want). 3 6 Simplify it and you get 1 2


What does it mean to find the compliment of the probability of an event?

The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.The complement (not compliment) of the probability of event A is 1 minus the probability of A: that is, it is the probability of A not happening or "not-A" happening.

Where can one find synthetic biology?

Synthetic biology combines biology and engineering. One example is inserting a gene from one animal into the DNA of a different animal. This is useful for gene therapy applications.
