You can express that in many different ways. For example, 0.8, 4/5, or 80% or 80 over 100

Probability formulas can be used to predict the probabilities that specific alleles will be passed on to offspring.

The two ways to express the atmospheric pressure at sea level are in millimeters of mercury (mmHg) or in hectopascals (hPa).
What is the probability of rolling an even with one roll of a numbers cube.
1+1 1*2
There are twenty six ways out of thirty six possible rolls of two dice to hit a number less than nine OR a seventy two percent probability.
The probability of throwing just one one with two dice can be calculated by considering the different ways it can occur. There are two ways to get one one: rolling a one on the first die and any number on the second die, or rolling any number on the first die and a one on the second die. There are a total of 36 possible outcomes when rolling two dice, so the probability is 2/36, which simplifies to 1/18.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
