Exercises 49-54 deal with sickle cell anemia, an inherited disease in which red blood cells become distorted and deprived of oxygen. Approximately 1 in every 500 African-American infants is born with the disease; only I in 160,000 white infants has the disease. A person with two sickle cell genes will have the disease, but a person with only one sickle cell gene will have a mild, nonfatal anemia called sickle cell trait. (Approximately 8%-10% of the African-American population has this trait.) Second Parent S s First S SS Ss Parent s sS ss If we use s to represent a sickle cell gene and S a healthy gene, the above table shows the four possibilities for the children of two Ss parents. Each parent has only one sickle cell gene, so each has the relatively mild sickle cell trait. Find the probability that these parents give birth to a child who Find the probability that these parents give birth to a child who is healthy.

ints) A common representation of data uses matrices and vectors, so it is helpful
to familiarize ourselves with linear algebra notation, as well as some simple operations.
Define a vector ♬ to be a column vector. Then, the following properties hold:
• cu with c some constant, is equal to a new vector where every element in cv is equal
to the corresponding element in & multiplied by c. For example, 2
2
=
● √₁ + √2 is equal to a new vector with elements equal to the elementwise addition of
₁ and 2. For example,
問
2+4-6
=
The above properties form our definition for a linear combination of vectors. √3 is a
linear combination of √₁ and √2 if √3 = a√₁ + b√2, where a and b are some constants.
Oftentimes, we stack column vectors to form a matrix. Define the column rank of
a matrix A to be equal to the maximal number of linearly independent columns in
A. A set of columns is linearly independent if no column can be written as a linear
combination of any other column(s) within the set. If all…
