Question

mr and mrs doran have a genetic history such that the probabilty that a child being born to them with a certain trait is 0.86 . if they have four chidren, what is the probabilty that exaclty zero of their three children will have the trait round the nearest thousandth

GPT-5 mini · Answer

I think there’s a small typo in your question (you mention both four and three children). Here are both interpretations.

Probability a child does NOT have the trait = 1 − 0.86 = 0.14.
For n children, P(exactly 0 have the trait) = (0.14)^n.

- If n = 4: P = 0.14^4 = 0.00038416 → rounded to the nearest thousandth = 0.000.
- If n = 3: P = 0.14^3 = 0.002744 → rounded to the nearest thousandth = 0.003.

Which version did you mean?

mr and mrs doran have a genetic history such that the probabilty that a child being born to them with a certain trait is 0.86 . if they have four chidren, what is the probabilty that exaclty zero of their three children will have the trait round the nearest thousandth
