. A husband and wife have a 2/3 probability of passing on brown eyes to their children. If they have three children, what is the probability that the children will all have brown eyes?
Homework Answers
X ~ Bin ( n, p)
Where n = 3 , p = 2/3
Binomial probability distribution is
P(X) = nCx * px *( 1 - p)n-x
P(X = 3) = 3C3 * ( 2/3)3 * (1 - 2/3)0
= 0.2963

If both a husband and wife carry genes for brown and blue eyes, genetic theory states that the probability the couple will have a blue-eyed child is 0:25. Suppose the couple plans to have 4 children. (a) Find the probability that the couple will have i. exactly two children with blue eyes ii. two or fewer children with blue eyes. (b) Find: i. the mean (expected) number of children with blue eyes, ii. the variance and standard deviation.

There are 24 people. 9 have green eyes, 4 have brown eyes, 5 have hazel eyes, and 6 have blue eyes. 3 people are then selected at random without replacement. What is the probability that 2 people selected have the same eye color, and that the other person selected has a different eye color
If both husband and wife are known to be heterozygous for the autosomal recessive condition of...
If both husband and wife are known to be heterozygous for the autosomal recessive condition of albinism, what is the probability that among their four children, three will be normal and one will have albinism? I know that each child has a 3/4 probability of being normal and 1/4 probability of having albinism. So is the answer 3/4 * 3/4 * 3/4 * 1/4? Or do you just do 3/4 * 3/4 * 3/4?

In a region, 80% of the population have brown eyes. If 15 people are randomly selected, find the probability that at least 13 of them have brown eyes. Is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? Why or why not? The probability that at least 13 of the 15 people selected have brown eyes is (Round to three decimal places as needed.)
