37/64
(You could have all three recessive (aacctt), and the probability of that genotype is ¼ x ¼ x ¼ = 1/64.
You could have two out of three recessive (aaccT-, aaC-tt, A-cctt), so the probability for each of those combinations is ¼ x ¼x ¾ = 3/64.
You could also have only one out of three recessive (aaC-T-, A-ccT-, A-C-tt), which is ¼ x ¾ x ¾ = 9/64.
By asking "at least one", you would use the sum rule to add all of these probabilities. So, 1/64 + 3/64 + 3/64 + 3/64 + 9/64 + 9/64 + 9/64 = 37/64)
Probability is the branch of arithmetic regarding numerical descriptions of ways probable an occasion is to occur, or how probably it's miles that a proposition is authentic. The probability of an occasion is a variety of among 0 and 1, wherein, roughly speak me, 0 suggests impossibility of the event and 1 shows fact.
What is a probability instance?
For instance, if you throw a die, then the probability of getting 1 is 1/6. Further, the probability of getting all the numbers from 2,three,4,5 and 6, separately is 1/6.
How do you give an explanation for probability?
A probability is a number that reflects the hazard or likelihood that a selected event will arise. Probability can be expressed as proportions that range from zero to 1, and that they also can be expressed as chances starting from 0% to a 100%.
